has been developed using a novel saturable absorber based on single-wall carbon
nanotubes incorporated in a polymer matrix. Laser pulses with the output energy up to 70 J
and the duration of 50 ps have been generated. A stable mode-locking regime has been
obtained with the pump frequency up to 1 kHz. The femtosecond time-resolved
measurements of the nonlinear absorption coefficient of the nanotube-based saturable …
