The experimental results show that the laser is an important assurance for doing 3 - D airborne information acquisition with high ground resolution.

The topic of this article mainly research and design about LD pumped solid laser high repetition frequency Q-switch system.

In this doubly Q-switched laser, the AO Q-switch is used to control the pulse repetition rate and allow the laser medium to store energy to ensure that the population inversion is fully saturated.
