Simulation of dual-wavelength pumped 3.5 µm CW laser operation of Er:Ca$F_{2}$ in waveguide configuration
Résumé
Based on a detailed spectroscopic investigation including excited-state absorption and fluorescence measurements, a simulation is developed to demonstrate multiwatt CW laser operation of an Er:Ca$F_{2}$ crystalline waveguide using single- or dual-wavelength pumping.
