Description
Technical field
The present invention relates to THz wave field, especially a kind of continuous terahertz emission source of wideband.
Background technology
THz waves (THz wave) or be the just quilt from middle and later periods the last century 80's for THz rays (Terahertz ray)
Definite designation, scientists are referred to as far ir ray before this.
THz wave refers to electromagnetic wave of the frequency in 0.1THz to 10THz ranges, and wavelength is situated between in 0.03mm to 3mm ranges
Between infrared ray wave band and millimeter wave.
From radiation wavelength, size belongs to transition region of the electronics to photonic propulsion, is between electronics and photon
Transition region of the macroscopic classical theories to Bcs Theory.
It is highly developed to the infrared technique and microwave technology of terahertz emission wave band both sides, but Terahertz Technology is also
Very not perfect, studying carefully its cause is handled with optical theory because wave band is neither entirely appropriate thus, is also not exclusively suitble to use microwave
Theory is studied, and the wave-length coverage of 0.03mm to 3mm, and just at present, range is too big, and in THz wave field
In, there is no the wavelength for which range clearly distinguished in this wave-length coverage to have special effect.
In view of the certain diseases of human body and THz wave close association, it has been found that wavelength is completely in 30u-1000u models
(in different moments, such THz wave has the continuous THz wave of wideband in enclosing in different wave length section at different temperatures
The wave state of different characteristics, and these wave states are completely in 30u-1000u this larger range, are defined with this described " wide
Frequently ", and these waves are continuous, defined " continuous " with this), medically have a great using effect, but regret
It is not find the method stablized and generate this continuous THz wave of wideband.
The mode of traditional generation THz wave has two classes, first, radiation source is electronically generated, electronics method
When generation radiation source frequency is more than 1T, output power and working efficiency drastically decline, the lost of life, and new structure is also hampered by micro-
The processing technology limit；Second is that optically generate radiation source, though optical means generates radiation source, that spectral range can be obtained is wider
Terahertz emission, but bulky expensive, consumption is greatly, using limited.
There is technological deficiency at present in both modes, also can not Simultaneous Stabilization generate we needed for 30u-1000u
(" simultaneously " word here, that is, be interpreted as continuous THz wave within the scope of this：The not single wave beam generated, from
The continuous one section of wave without fracture of 30u-1000u, has multiple wave crests, trough).
Invention content
In view of the problems of the existing technology, goal of the invention of the invention is to provide one kind can to generate wideband continuous
The terahertz emission source of 30u-1000u THz waves.
To achieve the goals above, the technical solution adopted by the present invention is：
A kind of continuous terahertz emission source of wideband comprising：

The arbitrary combination of amount, when produce electricl energy simultaneously, thermal energy, luminous energy and when THz wave, effect is best, but only produces electricl energy, heat
Can, luminous energy and THz wave one of those, two or three, be all feasible) and the crystal have an effect and generate terahertz
Hereby wave (excitation of first step Terahertz), the part THz wave that the excitation of first step Terahertz generates are exported towards radiation source outside,
Crystal is towards transport portion THz wave in radiation source simultaneously, and combines the energy for exciting body itself to send out, anti-by reflector
It penetrates final and touches the crystal, have an effect and generate Terahertz excitation (excitation of second step Terahertz), the first and second step is too
Hertz excitation, which combines, (still has THz wave and energy back flowing, meeting is again by reflector in the excitation of second step Terahertz
Reflection, theoretically for the first step and second step Terahertz excitation be a unlimited number of process), finally from the outer surface of crystal
