124 W diode-side-pumped Nd:YAG laser in dynamic fundamental mode
Optics & Laser Technology(2010)
Abstract
A high power dynamic fundamental mode Nd:YAG laser is experimentally demonstrated with a stagger-pumped laser module and a V-shaped resonator. The rod is pumped symmetrically by staggered bar modules. And dynamic fundamental mode is achieved under different pump levels. The maximal continuous wave (CW) output of 124W (M2=1.4) is achieved with a dual rod. Average output of 112W, pulse width of 120ns, pulse energy of 11.2mJ and peak power of 93kW are obtained in Q-switched operation of 10kHz.
