摘要

Simultaneous generation of green and blue laser beams based on a Nd:GdAl₃(BO₃)₄ (NGAB) crystal operating in the ⁴F_3/2→⁴I_11/2 laser channel and a KTiOPO₄ (KTP) crystal is reported. Pumped by a Ti:sapphire laser at 811 nm with absorbed pump power of 653 mW, a continuous wave green laser radiation with output power of 0.12 mW was generated by frequency doubling of the fundamental laser at 1062 nm in the KTP crystal. At the same time, a blue laser radiation with output power of 42 μW was also generated by self-sum-frequency-mixing of the fundamental laser at 1062 nm and the pump light in the NGAB crystal.
