Yb:CaF2 – Laser Crystal – Gain Medium – Customized Products
Yb:CaF2 is a new laser crystal formed by doping Yb into CaF2. The main emission peak is reported 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, it has the following characteristics:
- Low quantum defect
- A comparably long fluorescence lifetime
- High thermal conductivity
- 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 applications.
Furthermore, from the current point of view, the crystal growth technologies of Yb: CaF2 promise to be scalable, allowing for producing excellent optical quality material.
