A laser-diode end-pumped passively Q-switched intracavity doubling Nd:GdVO_4/KTP red laser with V~(3+):YAG saturable absorber

摘要

Using a V~(3+):YAG saturable absorber, we realize the running of a laser-diode end-pumped passively Q-switched intracavity-frequency-doubling Nd:GdVO_4/KTP red laser. Under the absorbed pump power of 9.45 W and with V~(3+):YAG initial transmission T _0 = 94%, the obtained average output power and pulse width were 610 mW and 15.09 ns with the repetition rate of 12.2 kHz, corresponding to the single pulse energy 50 μJ and the pulse peak power 3.34 kW.
