We report the performance of a laser-diode-pumped Nd:glass laser. Using the AM active mode-locking technique, pulses as short as 9 ps were obtained. The development of a high power (415 mW), high optical slope efficiency (32.4%) laser-diode-pumped Nd:glass laser using high power, broad stripe laser diodes as the pump source is described. Single frequency operation of the Nd:glass laser, using an acoustooptic modulator to ensure unidirectional operation in a ring laser configuration was investigated. An instantaneous line-width of less than 300 Hz was observed.
