Quantum confined nanocrystals of PbS in glass were used as intracavity saturable
absorbers to obtain passive continuous-wave mode locking in a Cr: forsterite laser. We
obtained near transformed-limited 4.6 ps laser pulses at 110 MHz repetition rate, and a wide
tunability range of 1207–1307 nm. The absorption saturation intensity of the quantum-dot
PbS doped glasses was measured to be 0.2 MW/cm2.© 1997 American Institute of Physics.
