Passive mode locking of a cw Nd:YLF laser with a nonlinear external coupled cavity.
Using an optical fiber as the nonlinear medium in an external cavity, we demonstrated passive mode locking of a cw Nd:YLF laser at a 1.053-microm wavelength. Nearly transform-limited pulses as short as 3.7 psec were obtained at a repetition rate of 76 MHz directly from the laser output without further compression. The average output power ranged from 1 to 7 W.
