Abstract

An acousto-optic modulator has been used to actively mode lock a KCl:Tl°(1) color-center laser at 1.5 μm. The color-center laser is capable of generating transform-limited pulses as short as 6 psec with 2-W cw pump power. Based on this actively mode-locked KCl:Tl°(1) laser a stable soliton laser has been operated, with performance similar to that of the synchronously pumped soliton laser.
