Amplification of ultrafast pulses in an extended Mamyshev regenerator

SPIE Proceedings Vol. 11260: Fiber Lasers XVII: Technology and Systems
Type: Zeitschriftenaufsatz (non-reviewed)
We present the characteristics of a high-energy ultrafast Yb-fiber laser system, based on a Mamyshev oscillator and a subsequently arranged fiber amplifier stage. The Mamyshev oscillator emits pulses at a repetition rate of 11 MHz and pulse energies of 31 nJ. These pulses are spectrally filtered and amplified in a Yb-doped fiber up to 1 μJ pulse energy which could be temporally dechirped to less than 50 fs autocorrelation duration. We discuss the scaling as well as limiting options related to pulse energies and duration.
