175 fs Tm:Lu2O3 laser at 2.07 µm mode-locked using single-walled carbon nanotubes

Opt Express. 2012 Feb 27;20(5):5313-8. doi: 10.1364/OE.20.005313.

Abstract

Single-walled carbon nanotube saturable absorbers were designed and fabricated for passive mode-locking of bulk lasers operating in the 2 μm spectral range. Mode-locked lasers based on Tm:Lu2O3 single crystals containing different Tm3+-doping concentrations were studied. Nearly transform-limited pulses as short as 175 fs at 2070 nm were generated at 88 MHz repetition rate.
