Abstract

High-power diode-pumped laser operation at 992 993 nm under a pumping wavelength of 981 of 986 nm is demonstrated with Yb : CaF 2 operating at cryogenic temperature ( 77 K ), leading to extremely low quantum defects of 1.2% and 0.7%, respectively. An average output power of 33 W has been produced with an optical efficiency of 35%. This represents, to the best of our knowledge, the best laser performance ever obtained at such low quantum defects on intense laser lines.
