Diode-pumped Nd:LuVO4-Nd:YVO4 laser at 492 nm with intracavity sum-frequency-mixing in LiB3O6

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 3 O 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.
