2.1mJ, 210W femtosecond fiber CPA system
Abstract
The coherent combining of ultrashort pulses is a concept for scaling the pulse energy and average power of laser systems emitting ultrashort pulses. This concept has already been demonstrated for two-channel systems. In this contribution we report on a four-channel system that delivers 2.1 mJ pulse energies at a repetition rate of 100 kHz and 210 W of average power after compression. A combination efficiency of 88% was achieved and this demonstrates the scalability of the combining approach to a larger number of channels.
