17 February 2017 Continuous wave operation of Nd:CaYAlO4 and Nd:ScYSiO5 lasers with hot band diode-pumping

Nd:SYSO and Nd:CALYO lasers were demonstrated with hot band pumping at 914 nm for the first time. The output power achieved was 201 mW centered at 1078.0 nm with slope efficiency of 18.6% for Nd:SYSO and 154 mW output centered at 1074.9 nm with 8.6% slope efficiency for Nd:CALYO. This pumping approach could offer further power scaling possibility due to the strongly reduced quantum defect and consequently lower thermal lensing.
