Abstract

A mode-locked, dual-wavelength pumped 3.5μm fiber laser using frequency shifted feedback utilizing an acoustooptic modulator is reported. Pulses of 3.8 ps with 9.7 nJ were obtained at a repetition rate of 37.75 MHz. The resulting peak power is 2.55kW. An electronically wavelength swept, mid-IR interrogator is built to characterize a mid-IR fiber Bragg grating.
