Q-switched and continuous-wave mode-locking of a diode-pumped Nd:Gd0.64Y0.36VO4-Cr:YAG laser

We report on a diode-pumped passively mode-locked Nd:Gd0.64Y0.36VO4 laser with a Cr:YAG saturable absorber. Q-switched mode locking (QML) with 90% modulation depth was obtained. The peak power of the mode-locked pulse near the maximum of the Q-switched envelope was estimated to be about 1.7 MW at th...

Zusammenfassung:We report on a diode-pumped passively mode-locked Nd:Gd0.64Y0.36VO4 laser with a Cr:YAG saturable absorber. Q-switched mode locking (QML) with 90% modulation depth was obtained. The peak power of the mode-locked pulse near the maximum of the Q-switched envelope was estimated to be about 1.7 MW at the pump power of 12 W. Besides QML, continuous-wave mode locking was also experimentally realized, for the first time to our knowledge, in the laser under a strong intracavity pulse energy fluence. The mode-locked pulse width is about 2.96 ps at a repetition rate of 161.3 MHz.
