Thermal analysis of diode-pumped femtosecond-laser-written Pr:LiLuF4 waveguide lasers

[EN]In this work we report a thermal stress test executed on high efficiency diode pumped waveguide lasers based on Pr:LiLuF4. Numerical simulations have been performed to estimate the core temperature. We demonstrated that no modifications in the output power, 275 mW at 604 nm and 310 mW at 721 nm,...
