Fibre Lasers: Promising Solutions

This work analyses promising solutions for controlling the output radiation properties of fibre lasers. The design of fibre lasers is radically different from that of other laser types. This is why many conventionally used solutions and approaches are incompatible with fibre lasers. Furthermore, fibre lasers following “all-fibre” designs also allow certain solutions that are impossible in other types of lasers. This work discusses those solutions, highlighting the promising applications for all-fibre lasers. Both the advantages and disadvantages of the very low sensitivity of the fibre laser cavities to the external factors are covered. Solutions that are already available commercially or may be expected to be in the near future are highlighted. Various aspects of sensor and communications applications of fibre lasers are discussed.
