Yb:CaF2 Laser Crystal

Nanjing Crylink Photonics Co.,Ltd

OVERVIEW

Yb: CaF2 is a new laser crystal which is formed by doping Yb into CaF2. The main emission peak are reported to be at 1033 nm and 1050 nm with the emission linewidth of 70 nm. Because of the absence of undesired loss transitions such as up-conversion, excited state-absorption and concentration quenching, their low quantum defect, a comparably long fluorescence lifetime, high thermal conductivity and wide emission linewidth, ytterbium-doped CaF2 is preferably utilized for high-power diode-pumped systems and laser amplifiers with high optical-to-optical conversion efficiencies, diode-pumped femtosecond (fs) lasers and amplifiers are one of the important potential application. Furthermore, at the current point of view the crystal growth technologies of Yb: CaF2 promise to be scalable, which allows for the production of excellent optical quality material.
