Single LD Pumped Nd: YAG Intra-Cavity Frequency Doubling Blue Pulse Lasers

Abstract:

To design and achieve a 473nm Q-switched blue laser, with single LD side-pumping structure, this dissertation firstly made 946nm operation of quasi-three-level system possible. After inserting the frequency doubling crystal-LBO and the passively Q-switched crystal-Cr: YAG into the laser cavity, the 473nm blue laser output was obtained at high repetition. When pumped currency reaches 4A, laser pulses of 25ns are generated with average power of 0.11w, repetition rate of 8.3 KHz which satisfies many applications’ requirements.
