Abstract

We report the room-temperature spectroscopic properties and continuous-wave laser operation of a new disordered crystal, Yb:Ca3(NbGa)2-xGa3O12. The peak absorption cross section is 3.3×10-20 cm2 at 973.5 nm; the emission band important for laser action is centered at 1028 nm with a peak cross section of 2.5×10-20 cm2. By diode end pumping, an output power of 1.9 W was achieved with a slope efficiency of 28.5%.
