Abstract
There has recently been much interest in the mode-locking of solid-state lasers using the technique of additive pulse mode-locking (APM),1 This technique has been shown to yield much shorter pulses than active mode-locking in a number of laser systems including Nd:YAG,2 Nd:YLF,3 and Nd:glass.4 Nd:glass is of particular interest for its very broad fluorescence linewidth (−19 nm), Krausz et al.4 have reported pulses as short as 380 fs from an APM Nd:glass laser pumped by a krypton-ion laser. This pump source was required to obtain high enough power from the Nd:glass laser for the APM process to be self-starting. In this paper we report subpicosecond operation of an APM laser-diode-pumped Nd:glass (i.e., all solid-state) laser.
