Abstract
Laser-diode (LD)-pumped high-power cw and passively Q-switched laser performance has been demonstrated with a disordered Nd-doped (Nd:LGS) crystal for the first time to our knowledge. A cw output power of was obtained under an absorbed pump power of with a slope efficiency of 30.2%. Using a Cr:YAG as a saturable absorber, the passively Q-switched laser was achieved. The maximum pulse energy, shortest pulse width, and highest peak power were measured to be , , and , respectively.
