Self-Starting Additive-Pulse Mode-Locked Diode-Pumped Nd:YAG Laser

摘要

A diode-pumped Nd:YAG laser is demonstrated by using self-starting additive-pulsemode locking with a nonlinear external cavity. Pulse durations of 2.7 psec are generated at an average output power of 25 mW without the need for active amplitude or phase modulation. Design and scaling issues for this technology are discussed. Diode pumping has emerged as an efficient and compact method for pumping solid state lasers. Numerous approaches have been demonstrated with both single and multiple diode-pump arrays to achieve high-efficiency operation in Nd:YAG, Nd:YLF, and other materials. Active mode locking by amplitude or phase modulation has been demonstrated in diode-pumped Nd:glass, Nd:YAG, and Nd:YLF. Reprints.
