An 8-W diode side pumped solid-state 593-nm laser

We report a double z-type folded plane-plane symmetrical cavity diode side pumped solid state yellow-orange laser at 593 nm by using intracavity sum-frequency mixing. By carefully designing the cavity and employing several techniques to increase sum-frequency efficiency, a Q-switched yellow-orange laser source, with an average output power of 8 W, a beam quality factor M2 = 4.86, and a repetition rate of 8 kHz is developed. In this paper, we first use 1338 and 1064 nm emissions of Nd:YAG crystal to generate 593 nm yellow-orange laser beam by intracavity sum-frequency mixing (SFM).
