Abstract
We present a diode-pumped Nd:glass fiber laser, emitting at 1060 nm, that i s passively mode locked by fast nonlinear loss in low-temperature-grown GaA s (LT-GaAs). This new mode-locking mechanism is based on intensity-dependen t defocusing in LT-GaAs that occurs after nonresonant generation of free ca rriers by two-photon absorption. Mode locking is self-starting and produces pulses as short as 4.1 ps. (C) 1999 Optical Society of America.
