Paper Abstract

We present results on a high-power, high-energy cladding-pumped fibre Raman laser. We first discuss fibre requirements and give a design rule. Then, experimentally, a pulsed cladding-pumped Raman fibre laser is demonstrated with up to 210 μJ high-brightness pulses. The fibre delivers pulses at the Stokes wavelength of 1112 nm, of 500 ns duration and 420 W peak power, with M2 = 1.8. The linewidth is 6.5 nm without any wavelength selection. Our result is the highest reported energy and peak power from any fibre Raman source and illustrates the power scalability capability of such devices.
