✦ Synopsis

We present for the first time a Nd:YAG laser emitting at 1064 nm intracavity pumped by a 946 nm diode-pumped Nd:YAG laser. A 809 nm laser diode is used to pump the first Nd:YAG crystal emitting at 946 nm, and the second Nd:YAG laser emitting at 1064 nm intracavity pumped at 946 nm. Intracavity sum-frequency mixing at 946 and 1064 nm was then realized in a LBO crystal to reach the cyan range. We obtained a continuous-wave output power of 485 mW at 501 nm with a pump laser diode emitting 25.4 W at 809 nm.

We present for the first time laser architecture to obtain continuous-wave yellow radiation at 594 nm. The choice of crystals (Nd:LuVO 4 for emission at 1343 nm and Nd:YAG for emission at 1064 nm) was guided by laser performance. A part of the pump power was then absorbed by the Nd:LuVO4 crystal, th
