Abstract
We demonstrated a laser-diode pumped Nd-doped yttrium gallium garnet crystal laser at for the first time to our knowledge. By suppressing the oscillation at about , continuous-wave output power of at was achieved. With a Cr:YAG as the saturable absorber, the passive Q-switching performance at this wavelength was obtained. The shortest pulse width and largest pulse energy were and , respectively. Laser radiation at this wavelength is an important source for detecting carbon monoxide poisoning by simple frequency doubling with a nonlinear crystal.
