Spectra and broad-spectral laser operation of a disordered Nd:LiLa(MoO4)2 crystal
2013
The crystal characteristics of a disordered Nd:LiLa(MoO4)2 laser crystal were investigated in detail, including its structure, absorption, emission and Raman scattering spectra. Laser operation, end-pumped by an 808 nm diode laser, has been demonstrated in both a concave-plano and plane-parallel resonator cavity. A broad-spectral dual-peak laser emission at 1061 nm and 1060 nm with a full width at half maximum of 2 nm was obtained in the experiment. A maximum output power of 267 mW was obtained in the concave-plano cavity. However, in the plane-parallel cavity, laser output of 381 mW was obtained, giving a slope efficiency of 14.5%. The results lay the groundwork for Raman, mode-locked and tunable laser applications generated by a Nd:LiLa(MoO4)2 laser crystal.
