We report on the mode-locking behavior of a 1.06-{mu}m Nd:YAG ring oscillator synchronously pumped by a 76-MHz, 20-psec dye laser at 0.59 {mu}m with an average power of 600 mW. Gain modulation is based on relaxation from the pump band to the upper laser level with time constant (minimum gain modulation time) of 470 psec; stable mode-locked operation is achieved with a gain modulation of only 10{sup {minus}4}. Preliminary results give a minimum pulse width of 140 psec and suggest a novel way of mode locking rare-earth waveguide lasers.
