Dynamic effects of power-scaling in high-power fibre-lasers
Supervisors: Prof Michalis N Zervas, Dr C Codemard
High performance, high power fibre lasers (FLs) are now well established as an extremely robust and reliable photon engine enabling a growing and diverse number of demanding industrial and medical applications.
Compared to rival technologies, such as CO2, LPSS, DPSS and disk lasers, FLs offer a number of unique characteristics and, in addition to enhancing existing applications, they have been very successful in enabling novel applications and thus increasing their market share. To continue this trend and further increase the FL functionality and stability, this project will consider in-depth the main issues related to power scaling in fibre lasers, such as suitable pumping schemes and pump requirements, fibre designs, limiting non-linear effects such as SRS and SBS.
Emphasis will be placed particularly to the study of dynamic effects related to output power stability of various advanced FL systems currently used in industry.
The project comprises theoretical analysis and understanding of the output power dynamics of various practical FL systems, as well as experimental investigation of the effects. It provides the opportunity to work closely with SPI Lasers plc, a leading FL manufacturer that has span out of the ORC.
