Dh. Sutter et al., THE SHORTEST KLM TI-SAPPHIRE LASER-PULSE STARTED BY A SEMICONDUCTOR SATURABLE ABSORBER MIRROR (SESAM), IEICE transactions on electronics, E81C(2), 1998, pp. 123-124
This paper summarizes our recent efforts in modelocking Ti:sapphire la
sers with semiconductor saturable absorber mirrors (SESAMs). We presen
t the shortest optical pulses ever generated directly from a laser. Th
e modelocking build-up time (T-BU) of 60 mu s is, to our knowledge, th
e shortest reported for a passively modelocked KLM laser to date.
