Abstract

The soliton laser [1] consists of a synch-pumped, mode-locked color center laser, tunable in the 1.5 μm region, coupled to a second cavity, containing a single mode, polarization preserving optical fiber. (See Fig. 1.) Feedback from the fiber, where pulse compression and soliton formation take place, enables the color center laser to produce transform limited pulses of ~sech² intensity profile and of any desired pulse width, down to about 100 fsec, through choice of the control fiber length.
