All-solid-state ultraviolet laser from micro-pulling down method frown Ce:LiCAF with direct pumping by the fourth harmonic of a Nd:YAG laser
Abstract
Laser emission at 290 nm from Ce3+:LiCaAlF6 efficiently grown by micro-pulling down method is demonstrated for the first time. Slope efficiency of 1.2% is obtained for single and dual side-pumping by the fourth harmonic of a Q-switched Nd:YAG laser. Slope efficiency can be improved by optimizing the doping concentration and side polishing.
