Physical fundamentals electronic control over generation properties of all-fibre mode-locked lasers

The mode-locked fibre laser technology has significantly simplified ultrashort-pulsed lasers. It introduced their design as maintenance-free systems approaching in convenience standard laboratory equipment or commercial devices, which do not require special training for their operation. These advantages find their fullest expression in all-fibre configurations where all intra-cavity laser radiation propagates within the core of the cavity fibre. This isolation of intra-cavity laser radiation has both advantages (higher stability, more compact implementation, etc.) and drawbacks: controlling generation properties of an all-fibre laser requires unusual means and methods, such as are not normally employed in non-fibre lasers. This review covers these special means and methods with an emphasis on the possibilities and advantages of electronic control over the generation parameters all-fibre mode-locked lasers.
