摘要：

Graphene was used for broadband saturable absorber and simultaneously applied in 1.06 μm Nd:YAG laser, 2 μm Tm:YAP laser and 1.55 μm Erbium-doped fiber laser. Taking advantage of the Atmospheric-pressure chemical vapor deposition method, acetylene and 25 μm thickness copper foil were applied as the carbon source and the catalyst respectively. Keeping them growing at the atmosphere of 1000 ℃ and ordinary atmospheric pressure. In the experiment of 1.06 μm Nd:YAG solid state laser, the repetition frequency is 360 kHz when the output power is 10 W. The shortest pulse duration is 240 ns and the single pulse energy is about 27 μJ, corresponding peak power is 115.7 W. In the experiment of 2 μm Tm:YAP solid state laser, a LD centered at 795 nm wavelength is employed for pump source. The pulse light is output via an end mirror with 10% transmittance, which generate the shortest Q-switching pulse with 1.4 μs pulse width. In the experiment of 1.55 μm erbium-doped ring cavity all fiber laser, a 1.25 m Erbium (Er3+) doped fiber is used for gain medium. The average mode-locking laser output power is 10 mW when pump power reach 100 mW. The output pulse duration and repetition frequency are about 314 ps and 20 MHz respectively. Therefore, the broadband saturable absorption of graphene was demonstrated, and stable short pulse laser was obtained in a series of experiments.
