Femtosecond Yb:YCOB laser pumped by narrow-stripe laser diode and passivelymodelocked using ion implanted saturable-absorber mirror

Abstract

The authors present, what they believe to be, the first femtosecond Yb:YCOB laser, pumped by a low-power, narrow-stripe laser diode. To facilitate modelocking, high-energy oxygen ion implantation of the saturable absorber is employed. 210 fs pulse generation at 16 mW average output power for 140 mW incident pump power is reported.
