Abstract

The invention discloses a pyrotechnic composition laser. The pyrotechnic composition laser comprises a light condensation cavity; a vibration exciter and a first protection tube are arranged in the light condensation cavity; a pyrotechnic composition column is arranged in the first protection tube; the pyrotechnic composition column is coated with a uniform energy-containing material layer; one end of the pyrotechnic composition column and one end of the first protection tube are fixed to the light condensation cavity through fixing devices; a trigger device is arranged at the other end of thefirst protection pipe; a firing pin for impacting the pyrotechnic composition column is arranged in the trigger device; the fixed end of the firing pin is connected to the inner wall of the trigger device through a spring; an inserting groove is formed in the fixed end; a trigger piece capable of being pulled out is arranged in the inserting groove; and the trigger piece penetrates through the trigger device. According to the technical schemes of the invention, chemical energy stored in pyrotechnic composition is utilized; the energy-containing material is deflagrated to serve as a pumping source, so that pumping energy density is large; the pumping source is easy to machine and form through a powdery viscous agent. Therefore, the laser of the invention has the advantages of large outputenergy, light weight, small size and convenience in integration.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a pyrotechnic powder laser. Background technique [0002] In the past, solid-state lasers often used electric light sources as pumping sources. Since solid-state electric light source lasers require a large amount of electric energy, they need to be equipped with a huge power supply system. At the same time, due to the huge heat generated during electro-optical conversion, a huge heat dissipation device is required. It will cause the size of the laser to be too large and the structure to be complicated. Contents of the invention [0003] Aiming at the above shortcomings of the prior art, the present invention provides a pyrotechnic powder laser with high energy density and low dependence on the external environment. [0004] In order to achieve the above-mentioned purpose of the invention, the technical scheme adopted in the present invention is: [0005] A pyrotechnic powder ...
