A laser-diode-pumped Nd:Glass laser: mode-locked, high power, and single frequency performance

The authors 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 linewidth of less than 300 Hz was observed.<
