ULTRA-SHORT PULSE MID-IR MODE-LOCKED LASER

机译:超短脉冲中红外锁模激光

摘要

A short-pulse mode-locked laser is configured with at least two reflective elements defining a resonant cavity therebetween, a laser gain element (“GE”) placed inside the resonant cavity at normal incidence and selected from transition metal doped II-VI materials; and an optical pump emitting pulsed output to synchronously or quasi-synchronously pump the GE at a pulse repetition rate frequency fpump, the pump being configured so that the fpump substantially matches an inversed round trip time in the resonant cavity flaser:fpump≈flaser=c/2L, where c is the speed of light, L is the length of the resonant cavity. The synchronous or quasi-synchronous pumping triggers and sustains a short-pulse emission of the laser with picosecond or femtosecond pulse durations.
