Abstract
We demonstrate high-power high-efficiency cavity-enhanced second harmonic generation of an in-house built ultra-high spectral density (SBS-suppressed) 1178nm narrowband Raman fibre amplifier. Up to 14.5W 589nm CW emission is achieved with linewidth Δν 5892a emission line. Further, we expect the technology to be extendable, at similar or higher powers, to wavelengths limited only by the seed-pump-pair availability.Keywords
