Abstract
We report on a passively mode-locked optically pumped GaSb-based semiconductor disk laser producing stable picosecond optical pulses at a wavelength. The gain mirror was comprised of a 15 quantum well InGaSb/GaSb structure. A fast semiconductor saturable absorber mirror with three quantum wells was used to attain self-starting mode-locked operation at a fundamental repetition rate of . The laser produced pulses with energy and a duration of within a factor of 2 of the Fourier limit.
