- S state ground state
- the linear absorption coefficient is defined by the absorption cross section per molecule and the number of molecules per unit volume. Since it is given by the product, in the excitation process as shown in FIG. 14, the linear absorption coefficient for the resonance wavelength ⁇ 2 to be irradiated subsequently depends on the intensity of the light of the wavelength ⁇ 1 which is irradiated first. That is, the linear absorption coefficient for the wavelength ⁇ 2 can be controlled by the intensity of the light of the wavelength ⁇ 1. This indicates that if the sample is irradiated with light of two wavelengths ⁇ 1 and ⁇ 2 and the transmission image at wavelength ⁇ 2 is taken, the contrast of the transmission image can be completely controlled by the light of wavelength ⁇ 1 ing.
- the emission intensity is proportional to the number of molecules in the S state. Therefore, control of the image contrast is possible even when used as a fluorescence microscope.

- the fluorescence itself is suppressed by 2 1 (fluorescence suppression effect), and the fluorescence is emitted only from the spatial region A
- the laser beam is condensed to a micro beam by a condensing lens and scanned on the observation sample, but the size of the micro beam at that time is the numerical aperture and wavelength of the condensing lens.
- the diffraction limit is determined by and, and in principle no further spatial resolution can be expected.
- two types of light of wavelength ⁇ 1 and wavelength ⁇ 2 are spatially well superimposed, and the fluorescence region is suppressed by irradiation of light of wavelength 2
- the fluorescent region can be narrower than the diffraction limit determined by the numerical aperture of the condensing lens and the wavelength, and the spatial resolution can be substantially improved.
- light of wavelength ⁇ 1 is referred to as pump light
- light of wavelength ⁇ 2 is referred to as erase light. Therefore, by utilizing this principle, it becomes possible to realize a super resolution microscope using double resonance absorption process exceeding the diffraction limit, for example, a super resolution fluorescence microscope.

- the microscope unit 50 is a so-called ordinary fluorescence microscope that reflects pump light and erase light incident from the scan unit 40 by the half mirror 8, and at least three ground states are obtained by the objective lens 9.
- the light is collected on the observation sample 10 containing molecules having an electronic state, and the fluorescence emitted from the observation sample 10 is collimated again by the objective lens 9 and reflected by the half mirror 8, so that the scanning unit 40 is again made.
- a part of the fluorescence passing through the half mirror 18 is guided to the eyepiece lens 11 so that it can be visually observed as a fluorescence image.
- phase plate 3, the beam combiner 4 and the objective lens 9 constitute an optical system for partially overlapping the pump light and the erase light and collecting the light on the observation sample 10.
- the wavelength of the pump light for exciting the molecules contained in the observation sample 10 to the first electron excited state having the excitation lifetime from the ground state is ⁇ .
- the wavelength of the erase light that excites the molecule from the first electron excited state to the second electron excited state with a higher energy level is ⁇ e
- the maximum photon flux on the observation sample surface of the pump light is Ip

Therefore, By measuring the fluorescence signal while scanning the pump light and the erase light with the scan unit 40, a super-resolution two-dimensional fluorescence image can be obtained.
- the intensity distribution (H (r)) of pump light on the sample surface the intensity distribution (G (r)) of erase light, and simultaneous irradiation of pump and erase light It is determined by the fluorescence suppression property of the sample in A, that is, dip ratio (P (Ie)).
- Ie is the photon flux of the erase light
- the dip ratio specifically indicates the fluorescence intensity ratio between the non-irradiation and the irradiation of the erase light.
- the fluorescence intensity profile (F (r)) at the time of simultaneous irradiation with erase light is the product of the fluorescence suppression characteristic and the pump light intensity, ie It is given by (2).
- a hollow Bessel primary beam having no light intensity on the optical axis is used as the erase light.
- the shape H (r) of the pump light is given by the equation (1).
- the Bessel beam used in the interlaced light is continuous from 0 to 2 ⁇ so as to orbit around the central axis of the beam as viewed from the cross section (pupil plane) of the beam.
- ⁇ and k are the wavelength and the wave number of the erase light.
- J n (z) is the n th e
- FIG. 6 shows an excitation diagram of dual-wavelength fluorescence dip spectroscopy. Generally, as shown in Fig. 6, when molecules in the ground state (S 1) are excited to the state S by pump light, the molecules
- the molecule is excited to a high quantum state (S 1), causing nonradiative relaxation to S and Tm triplet states n 0
- the dip ratio can be analyzed by determining this population. That is, since the amount obtained by integrating the population at observation time (T) is the observed fluorescence intensity, dip ratio P (Ie) is given by equation (4).
- n (t, Ie) is a population of the S state, which is a function of the photon flux of the erase light and the observation time. Furthermore, n (t, Ie) can be in S state (n (t, Ie)) and S state (n
- This rate equation is a linear, one-time differential equation and generally has a solution of the form
- n l (t, I e ) D 2 y t + D 22 e ⁇ + D 23 e ⁇ t , (6)

- ⁇ is the 3 ⁇ 3 coefficient matrix of equation (5)
- equation (6) is expressed as follows.
- the component of the exponent part of the equation (8) shows the change of population due to the transient transition immediately after the start of the pump light and erase light irradiation, and the other D continues the light irradiation and becomes steady state n3
- the inverse number of I ⁇ I corresponds to the time when the transition period ends, and in the case of most molecules, lnsec
- the population of S state can be represented in a specific form as follows.

- equation (12) can be approximated to the simpler practical equation (13) below.
- the amount is the total cross-sectional area that relaxes from the S state outside of the fluorescence process at the time of the erase light irradiation, that is, it is a very important spectroscopic parameter that determines the degree of the onset of fluorescence suppression along with the fluorescence lifetime.
- the microscope system can be constructed using the relationship of dip ratio of equation (14). Assuming that the optical system of the microscope has no aberration, the theoretically expected PSF can be calculated from the following equations (1), (2), (3), (12), (13) and (14). It can be obtained from equation (15).
- ⁇ and ⁇ are photon energy of pump light and erase light
- the Bessel beam is a non-spatial modulated ordinary light beam. In comparison with the mu, it has spread to double size.
- the light of the wavelength band longer than the pump light is used as the erase light in order to block the fluorescence emission due to the irradiation of the erase light, the light collection size becomes larger. Therefore, when the pump light and the erase light are condensed coaxially on the sample surface, most of the intensity distribution of the pump light is present inside the hole of the erase light. Therefore, Eq. (3) can be expanded approximately to the power of r near the optical axis, and the intensity profile of this hole can be approximated by a simple function to obtain Eq. (16) below.
- equation (14) As apparent from the equation (14), higher order terms of r 3 or more can be ignored as compared with the first term. In fact, the profile inside the hole can be approximately expressed by a quadratic function of r, as shown in FIG. Using this result, equation (15) can be simplified as equation (17) below.

- the numerator in order to efficiently induce the fluorescence suppression, it is advantageous in the equation (12) that the numerator be as small as possible with respect to the denominator.
- the fluorescence lifetime is unique to the sample molecule, in formula (12), the molecule is necessarily
- Equation (17) the improvement in resolution can be confirmed by super resolution microscopy because the half-width g of the Lorenian function, which is a modulation function represented by Equation (18), It is essential to be smaller than the half-width of the focused beam size of pump light given in 1).
- the half width ( ⁇ ) of the condensed beam size of the pump light is generally given by the following equation (21) according to Rayleigh's standard equation.
- the wavelength of the pump light is 532 nm
- the wavelength of the erase light is 599 nm

It is a thing. According to FIG. 7, choose the ⁇ 0. 7 X 10- 16 cm 2 before and after, the experiment results
- Rhodamine 6G since the absorption cross section to S force S and the stimulated emission cross section overlap in the wavelength 599 nm region, the exact ⁇ is unknown
- Figure 8 is a full Dad flux peak value of Iresu light 2. 1 X 10 25 photons / sec / cm 2 i.e. The PSF is shown for an electric field strength of 7 MWZ cm 2 .
- the solid thin lines and thick lines are PSFs in Eqs. (15) and (17), respectively. In the approximate formula, slight deviations are observed at the side lobes, but the profiles match well. According to Fig.
- FIG. 9 shows PSF when fluorescence spot images of super resolution microscopy were measured under the same conditions using fluorescent beads having a diameter of 175 ⁇ m.
- the measured profile indicated by the thick line is also in the low wrench ann type with the side lobes broadened as predicted by theoretical analysis.
- thin lines indicate the results of convolution of PSF according to the theoretical formula obtained in FIG. 8 with bead size. This theoretical calculation almost reproduces the experimental results.
- the approximate equation (17) is a rational function expressing PSF, and at the same time the physical model is a very clear and practical equation.
- Fig. 10 and Fig. 11 show the calculated profile and its half width.
- the photon flux of the start value of the condensed erase light reaches 5 ⁇ 10 25 photons / sec, it shrinks to the diffraction limit size of 1Z4.
- the half width is 70 nm, and a spatial resolution exceeding 100 nm which can not be achieved by the conventional optical microscope can be expected.
- the energy average intensity of the erase light at that time is about 20 mW when calculated.
- the ability to configure a system using such a simple laser is expected to reduce the cost of the system, and to control the laser wavefront unique to the present technology and the effects of the invention involved in practical application.
- This super-resolution microscope can be used to observe a sample with spatial resolution that exceeds the diffraction limit of the optical system.
