Abstract
A laser which utilizes a saturable absorber within a second resonator to obtain mode-locking for the production of short pulses. A second resonator which contains the saturable absorber and operates at the lasing frequency of the absorber intensifies the radiation from the absorber. The intensified radiation interacts with the absorber to reduce its effective lifetime and thus shorten its recovery time following saturation. The reduced lifetime absorber interacts with a laser amplifier to mode-lock the amplifier, thus producing short pulses of laser energy.
