Abstract

We report the production of mode-locked pulses as short as 8 psec by synchronous pumping in a laser using defect-perturbed Tl-atom color centers whose emission band, peaking at 1.52 μm, has a decay time of 1.6 μsec. However, pulse-width dependence on pump power and cavity loss is distinctly different from that obtained with dye lasers. Maximum cw output powers were in excess of 1 W. Details of center production and laser construction are given.
