Passive mode locking in a Ti:sapphire laser using a single-walled carbon nanotube saturable absorber at a wavelength of 810 nm.
We report mode locking in a Ti:sapphire (Ti:Sa) laser at the wavelength of 810 nm using a polymer film with single-walled carbon nanotubes (SWNTs) applied as a saturable absorber. Pulses with 600 fs duration and 0.4 nJ energy were generated from the Ti:Sa laser with polymer-SWNT composite film for cw passive mode locking.
