摘要：

The characteristics of a femtosecond forsterite Kerr-lens mode-locked laser pumped synchronously by an Nd:YAG laser are reported. Transform-limited femtosecond pulses of 60-fs (FWHM) duration with average TEM00 output powers of 200 mFV at 1.25 mu m were generated. Experimental studies of power stability and self-starting regime are described and a new experimental method to determine the nonlinear refractive index of the chromium-doped forsterite crystal (which is either the laser rod) is reported. We infer a value of 6 x 10-(16) cm(2)/W at 1.25 mu m, making possible Kerr-lens mode-locking. (C) 1997 Elsevier Science B.V.
