Technology of pyrotechnic-pumped laser based on laser ignition system

In order to study the output performance of pyrotechnic-pumped laser, the fireworks pump source and laser crystal rod matching experiments were researched in the pyrotechnic-pumped laser, and the fiber coupling output experiment of pyrotechnic-pumped laser was completed. The experimental results show that the output of pyrotechnic-pumped laser reaches more than 4.82 J,which satisfies the need for energy output of pyrotechnic-pumped laser initiation system;the fiber coupling output of pyrotechnic-pumped laser reaches more than 2.87J,and the efficiency of fiber coupling device reaches more than 50%, it can provide important technical support for the initiation systems used for the ejection of fighter hatch and pilot seat.
