Gj. Valentine et al., Femtosecond Yb : YCOB laser pumped by narrow-stripe laser diode and passively modelocked using ion implanted saturable-absorber mirror, ELECTR LETT, 36(19), 2000, pp. 1621-1623
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 mod
elocking, high-energy oxygen ion implantation of the saturable absorber is
employed. 210fs pulse generation at 16mW average output power for 140mW inc
ident pump power is reported.
