摘要：
We demonstrate the passive mode-locking of a diode-pumped Nd+3:YAG (central wavelength: 1.32 mu m; pulse duration: 50 ps; output energy: up to 70 mu J) laser using a polymer film containing single-wall carbon nanotubes. The mode-locking regime is stable at a pump repetition rate of up to 1 kHz. We also investigate the temporal evolution of the light-induced absorption change of the polymer film containing carbon nanotubes in the spectral range of 1.3-1.5 mu m by femtosecond time-resolved pump-probe measurements. The measurements reveal that light-induced transmission exhibits fast and slow components that last 280 fs and more than 10 ps, respectively. The third-order susceptibility of the polymer film containing single wall carbon nanotubes is as high as 10(-11) esu.
