YLPF femtosecond fiber lasers provide pulses with up to 50 μJ pulse energy with scalable average output power up to 50 W and customer selected pulse durations in the range of 250-500 fs at full operational repetition rate range of 50-5500 kHz. The all fiber format allows for the adjustment of peak power and/or pulse repetition rate without affecting any of the output beam parameters. IPG’s novel fiber lasers are much more efficient and compact than conventional lasers now on the market and are ideal for applications in precision micromachining. The excellent beam quality, ultrashort pulse duration and high pulse energy combine to provide peak power densities for micromachining virtually any metal, glass, ceramic, silicon or plastic.
