High-power diode-pumped Yb:GdCOB laser: from continuous-wave to femtosecond regime
Source abstract
Abstract
Abstract We present an efficient tunable continuous-wave diode-pumped Yb 3+ :Ca 4 GdO(BO 3 ) 3 (Yb:GdCOB) laser producing at room temperature up to 3.2 W average power with a slope efficiency of 80% when pumped with a 10 W laser diode. A large tunability from 1017 to 1086 nm is obtained. The broad emission spectrum has been used to develop a diode-pumped Yb:GdCOB femtosecond laser. The laser generated 90 fs pulses, at a center wavelength of 1045 nm. By using a semiconductor saturable absorber mirror (SESAM) for the mode locking, the average power was 40 mW and the repetition rate of 100 MHz.
