Time domain analysis of EO Q-switched laser pulse of Nd~(3+):YAG solid-state laser

Pulsed laser outputs with large energy and high peak power can be realized through the multi-laser precise synchronous synthesis technology with Nd3+:YAG solid-state laser.For the unit laser is EO Q-switched Nd3+:YAG solid-state laser with pulse widths of around 10 ns,the key technique is to perform precise electro-optical control of EO Q-switched circuit basing on precise detection of output laser pulse delay time.Through theoretical analysis and simulation on the setup mechanism of EO Q-switched laser pulse of Nd3+:YAG solid-state laser,the output characteristics of unit laser with various controlled parameters could be obtained.The experimental results indicate that the output waveforms of pulsed laser are identical with the simulation results,and achieve the expected effect.Technical conditions and feasibility of laser precise synchronous synthesis were put forward.Three units laser precise synchronous synthesis experiment was carried out.The synthesis precision around ±1 ns and synthesis efficiencies above 90% are achieved.
