Nonlinear optical absorption of single-wall carbon nanotubes in carboxymethylcellulose thin polymerfilm and its application as a saturable absorber for mode-locking in pulsed Nd:glass laser.
Nonlinear optical absorption of single-wall carbon nanotubes in carboxymethylcellulose (CMC) thin polymer film has been studied by the Z-scan method. Nonlinear saturated absorption at lambda=1080 nm was registered with saturation intensity of 170 MW/cm(2). Ultrashort pulses with duration of 3 ps were generated at lambda=1055 nm using this composite polymer film as a saturable absorber for passive mode locking in a neodymium glass laser.
