High Repetition Rate LDP-SHG Nd:YAG Laser

Abstract

The second harmonic of Nd:YAG laser with short output wavelengths is interesting for applications in optical data storage and laser-printer technology. High repetition rate green laser source also can be used to high speed scanning imaging and pumping tunable laser. Intracavity doubling in diode-pumped solid state lasers seem to be a promising approach for frequency doubling. One advantage with this configuration is that the difficulties with the narrow acceptance bandwidth of the nonlinear material can be half than in external frequency doubling.
