3W , 300μJ , 25ns pulsed 473nm blue laser based on actively Q-switched Nd : YAG single-crystal fiber oscillator at 946 nm
Résumé
We report the realization of a frequency doubled, actively Q-switched and polarized oscillator based on Nd:YAG single-crystal fiber.Alaser output of 8 W, 10 kHz, and 30 ns at 946nmis reported. The laser is extracavity frequency doubled in a BiBO crystal to obtain 3Wand 300 μJ of blue laser with a beam quality of M2y ? 1.12 and M2x ? 1.38. The obtained blue power is stable with a root-mean-square stability of less than 2% in 1 h. This is more than two times the previously reported average power and energy at 473 nm.
