Femtosecond Er laser system based on side-coupled fibers

  • Published:
Laser Physics

Abstract

A possibility of the femtosecond laser system with a pulse duration of about 300 fs and an energy of 150 nJ in a range of 1.6 μm based on side-coupled fibers one of which is doped with erbium and is pumped through cladding is demonstrated. The parameters of a ring master oscillator and an amplifier that make it possible to generate femtosecond pulses with a peak power of up to 450 kW are presented.
