摘要：

We report, to the best of our knowledge, the shortest femto-second pulses generated from a Kerr-lens mode-locked (KLM) Alexandrite laser operating near 750 nm. The Alexandrite gain medium was pumped with a continuous-wave (cw), 532 nm laser, and the performance of both the short and extended resonators was investigated. The use of an extended cavity eliminated the multi-wavelength spectral instabilities observed during the cw operation of the short cavity. Furthermore, since the repetition rate of the Alexandrite laser was reduced from 107 to 5.6 MHz, the resulting increase in the intracavity pulse energy provided enhanced Kerr nonlinearity and eliminated the Q-switching instabilities during mode- locked operation. The KLMMPC Alexandrite laser produced nearly transform-limited, 70 fs pulses at a pulse repetition rate of 5.6MHz with only 1 W of pump power. The time-bandwidth product was further measured to be 0.331. (C) 2018 Optical Society of America
