locked for the first time to the authors' knowledge. Reliable self-starting mode locking without
critical cavity alignment has been achieved with intracavity semiconductor saturable-
absorber mirrors and soliton mode locking. We generated pulses as short as 58?? fs with
the Yb: phosphate laser and 61?? fs with the Yb: silicate laser at average output powers of
65 and 53?? mW, respectively. The pulse repetition rate was 112?? MHz. Additionally, we …
Diode-pumped Yb: phosphate and Yb: silicate glass lasers have been passively mode
locked for the first time to the authors' knowledge. Reliable self-starting mode locking without
