Abstract

We use a new (to our knowledge) fabrication method of a single-walled carbon nanotube (SWCNT) absorber without polymer to sustain high-power illumination. Using a series of saturable absorbers (SAs) incorporating different amounts of SWCNTs, we demonstrate mode-locking for a Nd:GdVO4 laser in the 1μm spectral range. Continuous- wave mode-locking (CWML) pulses with a maximum output power of 3.6W at 1063nm and high noise extinction of 61dB has been achieved to give the highest pulse peak power of 3.6kW and pulse energy of 30nJ under 15W pumping. To our knowledge, this is the highest CWML output power with SWCNT-SAs reported. The measured nonlinear absorption of the SWCNT-SAs shows a modulation depth of 3% with subpicosecond recovery time.
