Spectroscopic properties and cw laser performance of a new Yb0.0054:Y0.3481Gd0.6465VO4 mixed crystal are reported. A sizable bistability is displayed in the laser operation with a bistability range of 1.9-3.4 W in terms of absorbed pump power, in which the coexistence and switching of the sigma and pi polarization states occur accompanied by wavelength shifting upon decreasing the pump power.

    ABSTRACT: Spectroscopic properties and continuous-wave laser performance of a new Yb(0.009):Y(0.575)Gd(0.416)VO(4) mixed vanadate crystal are reported. Purely sigma-polarized laser oscillation at 1013-1009.5 nm, with quantum defect lower than 3%, is demonstrated at room temperature in free running mode under diode pumping, producing an output power of 1.55 W with optical-to-optical and slope efficiencies of 19% and 32%, respectively. At longer wavelengths where the pi-polarized oscillation exhibited higher gain, the output power reached 2.5 W, with a slope efficiency of 41%.

    ABSTRACT: We report distinct laser performance of Yb:GdCa(4)O(BO(3))(3) crystals cut along different principal optical axes using an unpolarized diode pump. The continuous-wave (cw) laser oscillation generated with y-cut crystal is polarized either with E parallel x or with E parallel z depending on the output coupling (T) utilized; a specific T=3% leads to a special situation in which the two orthogonal polarization states coexist oscillating at different wavelengths. The laser oscillation achieved with x- and z-cut crystals is also polarized, but with a fixed polarization of E parallel z and E parallel x, respectively. The most efficient laser operation is obtained with the y-cut crystal, generating a cw output power of 7.35 W at 1083-1085 nm with an optical-to-optical efficiency of 63%, the slope efficiency being as high as 84%.

    ABSTRACT: We have studied the effect of optical bistability exhibited in the laser oscillation of Yb:GdVO4 crystal, revealing the complexities arising from the coexistence and switching of σ and π polarization states characteristic of this crystal. In terms of absorbed pump power, the range for bistable operation can be in excess of 1 W, while the output power generated at the up-threshold can reach as high as 0.71 W. The studies also show significant influence of the Yb concentration, the crystal thickness, the output coupling, and the resonator configuration on the bistable laser operation.
