摘要：

We present a new and simple method for the fabrication of carbon nanotube (CNT) films for fiber laser mode-locking. Using a microtip, we deposited a droplet of CNT/polymer suspension directly onto a fiber ferrule. Typical film thicknesses as low as 20 mu m are measured. Thicker films are easily achievable through the deposition of additional droplets, which allow for fine tuning the transmittance of the film. Based on a 40-mg/ml CNT concentration film used in an Erbium-doped fiber laser, we obtain mode-locked pulses with a bandwidth of 10.2 nm and duration of 364 fs.
