Abstract

As self-frequency-doubled (SFD) lasers are potentially more compact and less costly, the novel high efficient SFD lasers attract great interest. Here we report the spectroscopic properties under room temperature of a new self-frequency-double Yb³⁺ doped Gd_0.2Y_0.75(BO₃)₄ (Yb:GdYAB) single crystal grown in Shandong University. Both foundation and self-double-frequency continuous-wave laser were operated with a high-power diode. A foundation laser slope efficiency of 82% with respect to the absorbed 975 nm pump power of 2.62 W was obtained. The center wavelength at 1040nm was generated and the laser wavelength could be tuned from 1020 to 1064 nm. And thus, the broadly emission spectra was advantageous for the production of short-pulse diode-pumped solid state lasers. Self-double-frequency green light was also obtained under pump power of only 274mW with a flat-concave cavity. The maximal output power was 330mW when pumped power was 2.62 W. A diode-to-green optical conversion efficient of 12.6% was achieved. The results demonstrated that the Yb:GdYAB crystals are potential candidates for efficient microchip both 1 μm and visible laser media.
