In first step, designed a single Nd:YAG laser oscillator with 400 mj output energy, and at next step with GTR-KTP we generate second harmonic of it. At design of resonator we optimize the resonator with respect to thermal lensing and threshold of damage of optical element LA eng UL http://opsi.ir/article-1-1183-en.html M3 ER -
