Femtosecond laser based on a multicomponent fiber with a 3 wt.% Er-doped phosphate core and silica cladding. (25th June 2019) - Denker, B I
Abstract: To the best of our knowledge, we present the first demonstration of a passively mode-locked ring laser based on a multicomponent fiber with silica cladding and a 3 wt.% Er-doped phosphate core. The active fiber length was about 19 cm. The laser emitted 570 fs pulses at a repetition rate of 23.9 MHz with an average output power of 1.4 mW. The pulse energy was about 60 pJ.
