Diode-pumped Yb:phosphate and Yb:silicate glass lasers have been passively mode locked for the first time to authors' knowledge. Reliable self-starting locking without critical cavity alignment has achieved with intracavity semiconductor saturable-absorber mirrors soliton locking. We generated pulses as short 58 fs laser 61 at average output powers of 65 53 mW, respectively. The pulse repetition rate was 112 MHz. Additionally, we demonstrated tunability femtosecond from 1025 1065 nm 1030 1082 glasses. highest mode-locked power 405 183-fs phosphate glass. diode pump 1.68 W, corresponding 24% optical-to-optical efficiency. cw 510 mW same incident power.
