摘要：

A group-velocity mismatch compensation technique has been applied to cw Nd:YAG and Nd:YLF lasers mode locked by use of the nonlinear reflectivity or the nonlinear phase shift that arises from the intracavity parametric interaction of a pulse with its second harmonic. An intracavity birefringent plate, which delays the fundamental wavelength pulse with respect to the second-harmonic pulse, compensates for the opposite effect that arises in the second-harmonic crystal. Compensation reduces the pulse duration by a factor of 2 and allows pulses of 5.1 and 5.9 ps to be obtained from Nd:YLF and Nd:YAG lasers, respectively. (C) 1995 Optical Society of America
