Problems solved by technology

The problems of this method of Q-switching are: (1) After the Q-switching box is closed and put into the resonator, the dye concentration cannot be changed; (2) External factors such as strong laser radiation will gradually deteriorate the dye and affect the stability of the Q value (3) After the dye has deteriorated, if you want to replace the Q-switching box, you need to disassemble the resonant cavity, which is time-consuming and labor-intensive and very inconvenient

Embodiment Construction

[0013] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown, the basic structure of the Q-switching pool of the present invention is two cylinders inside and outside, mainly composed of the following parts: inner cylinder 1, outer cylinder 2, flange 5, focusing lens 6, collimating lens 4, flange cover 8, and the supercritical fluid connection 11 and the constant temperature bath inlet connection 3. Stainless steel is used as the metal material, polymer materials with better elasticity are used for sealing, and suitable optical materials are used for the lens.

[0015] The inner cylinder is filled with SCFNCP, and the jacket between the outer cylinder and the inner cylinder is used as a circulating constant temperature bath for the SCFNCP in the inner cylinder as the SBS pool.

[0016] Before the flange 5 is welded to the inner cylinder 1, the parallelism between the focusing lens 6 and...

Abstract

It is an impulse laser Q adjusting pool belonging to laser technique, which has the following: inner cylinder with both ends sealed with flange, where locates a focus lens at center holes of two flanges and a racket connected with the flange inside the inner cylinder with a calibration lens; an outer cylinder outside the inner cylinder to form a clamp cover between inner and outer cylinders; a ultra-limit fluid joint tube on the walls of inner cylinder to connect ultra-limit fluid generator; temperature constant joint tube and exit tube on the walls of outer cylinder.

Description

technical field [0001] The invention belongs to the technical field of lasers, in particular to a Q-switching device for pulsed lasers. Background technique [0002] An effective way to increase pulsed laser energy and peak power is Q-switching to apply a wide range of CO 2 Take the pulsed laser as an example. The traditional Q-switching method is to place a dye Q-switching box in the resonator. The Q-switching box is a disc-shaped box with a light-through window, which is closed by a plane mirror; The saturated absorption light intensity Is of the dye in the box, and the required Is can be obtained by changing the concentration of the dye. The problems of this Q-switching method are: (1) After the Q-switching box is closed and put into the resonant cavity, the dye concentration cannot be changed; (2) External factors such as strong laser radiation will gradually deteriorate the dye and affect the stability of the Q value (3) After the dye deteriorates, if the Q-switching ...
