Laser-diode-pumped green laser for optical storage

Abstract

We have developed three types of green solid state lasers pumped by laser diodes. A green laser outputs up to 24.5 mW at 532 nm with Nd:YAG/KTP crystal, the second outputs up to 19 mW with Nd:YVO4/KTP crystal and the third up to 29 mW with LNYAB crystal. The experiments setups and results are discussed. Comparison of these three kinds of lasers are presented.
