Diode-Pumped Nd:LuVO_4–Nd:YVO_4 Laser at 492 nm with Intracavity Sum-Frequency-Mixing in LiB_3O_6

摘要

We present for the first time a Nd:YVO_4 laser emitting at 1064 nm intracavity pumped by a 916 nm diode-pumped Nd:LuVO_4 laser. A 809 nm laser diode is used to pump the Nd:LuVO_4 crystal emitting at 916 nm, a Nd:YVO_4 laser crystal was pumped at 916 nm and lased at 1064 nm. Intracavity sum-frequency mixing at 916 and 1064 nm was then realized in a LiB_3O_6 (LBO) crystal to reach the blue range. We obtained a continuous-wave output power of 216 mW at 492 nm under 19.6 W of incident pump power at 809 nm.
