Abstract
Stable transform limited femtosecond pulses were generated from a self mode-locked chromium-doped forsterite laser. The forsterite laser was synchronously pumped by a CW mode-locked Nd:YAG laser which generated picosecond pulses (200-300 ps) and provided the starting mechanism for self mode-locked operation. Pulses with FWHM of 105 fs were originally generated which were reduced to 50 fs by using prisms that compensated for quadratic phase but introduced minimum cubic phase. The self mode-locked forsterite laser was tune from 1240 to 1270 nm.
