Abstract:
Nd:YAG laser is one of the most applicable lasers on laser researches where it’s basic wavelength and higher harmonics are used on different laser projects. It should be realized that it’s basic output has a wide pulse duration and lower peak power. Therefore, in order to increase the peak power the pulse duration is reduced by Q-switching.
In this project, in the first step, based on flash-lamp pump Nd:YAG laser a 600 mj energy per 60 µs pulse is constructed. Then a pulse duration is shorten by order of more than 3000 via electro-optics Q-switching system where we could reach up to 19 ns pulses and laser peak power is increased up to several megawatts
