Fiber Lasers

Over the last 10 years fiber lasers have migrated from milliWatts to tens of kilowatts of output optical power and became the most exciting technology on the laser market right now. Currently fiber laser and amplifier technology is one of the major players in the field of material processing, telecommunications and defense applications. Efficiency, beam quality, wavelength choice, compactness, maintenance free operation, etc. makes it a unique source of choice for the industry. A variety of new applications have been developed and implemented in the field over recent years and continue to grow very fast. At this presentation we will give a historical overview, current results, market situation as well as new applications and a potential markets overview.
