Abstract—An all-solid-state single-longitudinal-mode (SLM) laser at 500.8 nm with 830 mW output power
has been demonstrated for the first time. By using a new resonator for doubly resonant, Nd:GdVO₄ and Nd:YAG
were pumped by two laser diode arrays coupled by optical fiber, respectively. In the two sub-cavities, SLM
wavelengths of 1064 and 946 nm were induced by using the twisted-mode technique and then mixed into SLM
500.8 nm laser with sum-frequency technology. The SLM 500.8 nm laser output of 830 mW was obtained at
the incident pump power of 20 W for Nd:GdVO₄ and 23 W for Nd:YAG. The experimental results showed that
the intracavity sum-frequency mixing by twisted-mode technique is an effective method for SLM 500.8 nm
laser.
