Efficient, tunable, zero-line-diode-pumped, continuous-wave Yb3+:Ca4LnO(BO3)3 (Ln=Gd,Y) lasers at room temperature, application to miniature lasers

Abstract : We demonstrate an efficient cw 976-nm-diode-pumped Yb31:Ca4GdO(BO3)3 laser. At room temperature we obtained 814 mW of power with a slope efficiency of 77% and a small-signal gain per round trip of 1.67. We also demonstrate that the Yb31:Ca4LnO(BO3)3 (Ln 5 Gd, Y) crystals are suitable for a plano-plano microchiptype cavity. With this microlaser we have obtained an average power of 300 mW, which corresponds to an optical-optical conversion efficiency of 27%
