A diode-pumped doubly Q-switched c-cut Nd:GdVO 4 laser at 1.34μm with acousto-optic (AO) modulator and V 3+ :YAG saturable absorber is demonstrated. This doubly Q-switched laser can generate shorter pulse width and higher peak power than the singly Q-switched laser only with an AO modulator or a V 3+ :YAG saturable absorber. By considering the thermal lens effect of the laser...
Laser performance with the mixed Nd:Lu 0.15 Y 0.85 VO 4 crystal at 1.34μm wavelength has been demonstrated. The continuous wave (cw) operation was carried out in a simple plano-concave resonator with an optical conversion efficiency of 23% and a slop efficiency of 25%. At a pump power of 6.78W, the Q-switched pulses with the largest average output power of 349mW, the shortest...
