Continuous wave and Q-switched laser output of laser-diode-end-pumped disordered Nd:LGS laser.
Laser-diode (LD)-pumped high-power cw and passively Q-switched laser performance has been demonstrated with a disordered Nd-doped La(3)Ga(5)SiO(14) (Nd:LGS) crystal for the first time to our knowledge. A cw output power of 2.25 W was obtained under an absorbed pump power of 7.84 W 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 117.5 muJ, 23.4 ns, and 5.02 kW, respectively.
