22 February 2018Mode-locked NALM-based fibre laser with controllable operation regimes
This work reports, for the first time, the results of the development and study of an Yb-fibre master oscillator, in which a variety of mode-locked regimes may be created in a controlled way electronically, including regimes producing picosecond single-scale pulses and double-scale trains. The possibility of electronic switching among generation regimes of the developed laser relies on a non-linear amplifying loop mirror of a new generation featuring two stretches of active fibre with two independently controlled pump modules. This work presents a detailed description of the experimental set-up and discusses the application prospects of the newly developed universal laser.
