WebOct 1, 2024 · By continuing to optimize the doping concentration of crystal and the experimental conditions of laser, it is expected to obtain better performance of 2.8 μm laser output. When Er:CaF 2 was pumped by 980 nm LD to generate a 2.8 μm laser, it can be considered as a three-level system with ignoring non-radiative transition. WebSingle-crystal calcium fluoride (CaF2) is the most suitable material for a highly efficient optical micro-resonator. The CaF2 resonator can only be manufactured by ultra-precision machining processes, because its crystal anisotropy does not allow the application of chemical etching. However, the optical micro-resonator's performance depends ...
