Abstract

A femtosecond thulium-doped passively modelocked fiber laser with internal dispersion compensation is presented. It generates pulses at a center wavelength of 1985 nm with a dechirped pulse duration of 320 fs and an energy of 3.5 nJ. Pulsed operation is achieved using additive pulse mode locking, dispersion compensation is facilitated by an internal grating arrangement.
