Abstract

Broadband pulsed laser generation is demonstrated by using mesoporous carbon nanospheres (MCNs) as saturable absorbers (SAs). The MCNs are prepared by a “silica-assisted” method, and then mixed with sodium carboxymethylcellulose (NaCMC) to form the MCNs film. The film not only shows strong absorption from visible to mid-infrared spectral region, but also possesses the nonlinear saturable absorption properties. As the MCNs film is inserted into the laser cavity, a mode-locked laser at 1 µm and Q-switched lasers at 1.56 and 2 µm are realized, respectively. In addition, by depositing the MCNs onto tapered fiber as an SA, a mode-locked fiber laser at 2 µm is also demonstrated. The results show that MCNs are promising SA material for broadband pulsed laser generation.
