TABLE 2.

Benefits associated with Fibre lasers over traditional solid-state and OPO lasers (adapted from ref (RPMC, 2020))

Solid-State/OPO-Based Lasers	Femtosecond Fibre Lasers
Large cumbersome design	Lightweight, up to 10x smaller
Expensive	Affordable
Less consistent pulse duration	Pulse duration always maintained
Lower power at long wavelengths (crystal-based amplifiers)	Maintains high power at long wavelengths (up to 4W at 920 nm)
Water-cooled	Air-cooled
High cost of ownership	Low maintenance and engineer fees (fast return on investment potential)
