All-solid and cylindrical design ensures the suitability for mass scale production with the added benefit of all-fiberized device structure. A compact master oscillator power amplifier (MOPA) has been built using this fiber delivering ~23.5 ps pulses at 13.5 MHz repetition rate delivering up to ~52 W of average output power corresponding to a pulse energy of ~3.8 µJ and peak power of >160 kW, while maintaining ~76% slope efficiency.
The output beam exhibits a polarization extinction ratio of more than 15 dB and a M2 less than 1.15.

Abstract

We experimentally demonstrate an all-solid Yb-doped 30 µm core diameter single trench fiber. Measurements ensure a robust effective single-mode operation without the need of tight coiling as required for conventional fibers thanks to the ultralow NA ~0.038 and resonant ring surrounding the core. All-solid and cylindrical design ensures the suitability for mass scale production with the added benefit of all-fiberized device structure. A compact master oscillator power amplifier (MOPA) has been built using this fiber delivering ~23.5 ps pulses at 13.5 MHz repetition rate delivering up to ~52 W of average output power corresponding to a pulse energy of ~3.8 µJ and peak power of >160 kW, while maintaining ~76% slope efficiency.
The output beam exhibits a polarization extinction ratio of more than 15 dB and a M2 less than 1.15.
