LaF3–Er3+ Crystal as Materials for MIR-Lasing Operating

Abstract—

The possibilities of LaF₃–Er³⁺crystal to obtain cascade lasing with CW pumping at 0.52 μm wavelength are considered. The conditions for the formation of inverse populations between Stark levels of neighboring manifolds are determined. It is shown that, at 100 K and CW pump intensity \({{J}_{p}} \geqslant 350\,\,{{\text{W}} \mathord{\left/ {\vphantom {{\text{W}} {{\text{c}}{{{\text{m}}}^{2}}}}} \right. \kern-0em} {{\text{c}}{{{\text{m}}}^{2}}}}\), it is possible to obtain simultaneously laser radiation at 3.21 and 2.88 μm wavelengths.
