Abstract

We generated 2 nJ, ∼690 fs pulses with 10 MHz repetition rate from a linear cavity mode-locked Er3+-doped fiber laser with a fiber taper embedded in carbon nanotubes (CNTs)/polymer composite. Evanescent field out of the taper section can interact with CNTs to see saturation of absorption. With the fiber based saturable absorber this laser has simple and robust all-fiber configuration comparing to traditional linear cavity mode-locked lasers with semiconductor saturable absorbers. In addition, we have demonstrated a mode-locked ring laser, with a similar saturable absorber, by using an ion-exchanged Er3+-Yb3+-codoped planar waveguide as the gain medium.
