Efficient and tunable continuous-wave diode-pumped Yb3+:Ca4GdO(BO3)3 laser

Abstract : A Yb31:Ca4GdO(BO3)3 (Yb:GdCOB) crystal has been diode pumped for the first time to our knowledge. We obtained 47.5% slope efficiency at 6 °C, producing 191 mW of power at 1050 nm, with a 2.4% output coupler. Temperature does not significantly affect the laser performance: At room temperature we still obtained 180mWof power for the same cavity. We achieved tunability of the Yb:GdCOB laser from 1035 to 1088 nm with a 1.7% output coupler and 100-nm tunability with a low-transmission output coupling (T 5 0.03%)
