Abstract
This paper presents the experimental results obtained in the development of novel optical fiber lasers architectures operating in continuous-wave and pulsed regimes. The first laser shown is an actively Q-switched operating at 1565 nm with a double-clad fiber doped with Er3+/Yb3+, pulse widths in the order of hundreds of ns, repetition rate from 200 kHz to 310 kHz, and average power up to 2.5 W. The second architecture is a passive mode-locked laser with higher harmonics generation. Output characteristics are; center wavelengths 1563 nm, noise-like pulses with durations around 80 ns, harmonics evolution up to the order 1270, and repetition rates to 259 MHz. The results presented seek to provide a comparison between two types of optical fiber lasers of great technological interest.
