Abstract

Amplified ultrashort pulses at 2 μm are of great interest for atmospheric sensing, medical, and materials processing applications. We describe the generation and amplification of femtosecond 2 μm pulses in thulium doped silica fiber. Mode-locked eye-safe laser pulses at ∼2 μm were generated in a Tm:fiber oscillator using a single-walled carbon nanotube saturable absorber. Stable mode-locking was achieved at a repetition rate of 70 MHz with soliton pulses reaching energies of ∼40 pJ with a spectral bandwidth of ∼8 nm. Autocorrelation measurements indicated bandwidth limited pulses of ∼500 fs duration. This oscillator was used to seed a Tm:fiber amplifier in both free space and fiber coupled configurations. Effects of dispersion compensation and pulse amplification are reported.
