High power dissipative soliton laser using chirally-coupled core fiber

Abstract

We report the energy scaling of mode-locked fiber lasers using a large-mode area chirally-coupled core fiber. This is a demonstration of the scaling of ultrafast fiber oscillators to large cores in an all-solid glass package that holds the lowest order fiber mode while maintaining compatibility with fiber fusion technology. An all-normal dispersion cavity design yields pulse energies above 40 nJ that dechirp to durations below 200 fs. Using lower net dispersion, pulses dechirping close to 100 fs are obtained with pump limited energies. Effectively single-mode operation is confirmed by beam quality as well as spectral interference measurements.

“…Dissipative solitons (DSs) have attracted much attention due to the balance between the ultrashort pulse and large energy. [1,2] The excellent output performance is suitable for applications ranging from optical communication to ultraprecision machining. [3,4] To design a DSs fiber laser, there are several critical factors that require careful consideration.…”
