Abstract
We report a quasi-three-level laser pumped Ca4GdO(BO3)3 (Yb:GdCOB) tunable laser based on the transition from the 2F5/2 level to the 2F7/2 level. By adjusting the 902 nm pump power, a continuous waves Yb:GdCOB laser was obtained with the near-infrared wavelengths shifting from 1030 nm to 1036 nm. The highest tuning power of 2.5 W was achieved with a slope efficiency of 19.9%. To our knowledge, it is the first tunable Yb:GdCOB laser to be realized by adjusting the pump power. This work provides a novel method to generate tunable solid-state lasers with a compact and simple structure.
