Picosecond Fiber Laser Breaks 100-W Barrier

Facebook X LinkedIn Email
Fiber MOPA has 1-GHz repetition rate with average power of more than 300 W.

Breck Hitz

Fiber lasers already have proved capable of remarkable continuous-wave performance, generating more than 1 kW with excellent beam quality. Scientists at the University of Southampton and at Southampton Photonics in the UK now have shown that fiber technology also can scale picosecond sources to average powers of more than 100 W. They have obtained 321 W from such a laser and believe that it could readily be boosted to 500 W. Previous picosecond fiber lasers have been limited by nonlinear effects to average outputs of ~100 W. Figure 1. The master oscillator power amplifier (MOPA)...Read full article
