One hundred and twenty one W green laser generation from a diode-side-pumped Nd:YAG laser by use of a dual-V-shaped configuration
To ensure high-average-power and long-lifetime second harmonic generation, a dual-V-shaped configuration was designed. In this thermally near-unstable resonator, large fundamental mode size in Nd:YAG rod and small one in LBO crystal could be generated, which improved both the beam quality and the po...

Zusammenfassung: | To ensure high-average-power and long-lifetime second harmonic generation, a dual-V-shaped configuration was designed. In this thermally near-unstable resonator, large fundamental mode size in Nd:YAG rod and small one in LBO crystal could be generated, which improved both the beam quality and the power density. A green output power of 121
W with pulse width of 68
ns and repetition rate of 10
kHz was obtained. To the best of our knowledge, the dual-V-shaped configuration is the first time used for green laser with average output power of more than 100
