Definitions

  • the present invention relates to a method and a device for exciting a flash tube. It finds an application in the optical pumping of lasers.
  • a parallel tripping circuit has the disadvantage of requiring a winding wound around the flash tube or arranged in the vicinity thereof. This winding disturbs the optical elements which are located in the immediate vicinity of the flash tube.
  • the electrical control pulse may cause microfractures in the tube.
  • the object of the present invention is precisely to avoid these drawbacks.
  • the device represented in FIG. 1 comprises a capacitor 10, a source 12 of direct voltage connected to the capacitor by a resistor 14 and a coaxial line 16 connecting the capacitor 10 to a flash tube 18.
  • a means 20 which according to the invention comprises a source 22 of radiation 24.
  • This source may for example be an ultraviolet source. It is supplied by means 26.
  • the radiation 24 emitted by the source 22 is directed towards the flash tube 18 (if necessary by suitable optics not shown).
  • a radiation source which is very suitable for this application is the mercury vapor lamp.
  • the supply circuit 26 of the lamp 22 can be constituted by a continuous or pulsed supply.
  • FIG. 2 illustrates a possible application of the invention to the production of a high power solid-state laser.
  • This laser comprises a rod of doped glass 30 surrounded by a transparent glass sheath 32, and six flash tubes 34. Each tube is associated with a reflector 36, which is pierced with a slot 38 which allows the passage of radiation coming from a lamp 40, in particular from ultraviolet radiation.
  • an electrical triggering device of the kind mentioned above.
  • the optical radiation is applied before or during the control of the electrical triggering means.
  • the action of the second means is facilitated by the means of the invention.
  • the mechanism by which the optical radiation passing through the flash tube causes or promotes the initiation of the discharge therein is not completely understood, it may be thought that the gas is the site of a partial photoionization which gives rise to electrons, which are responsible for initiating the discharge.
