We develop a novel solid state fibre laser system, AFIRE, for the purposes of laser guidestar (LGS) assisted adaptive optics (AO), based on the second harmonic generation (SHG) from a high-power (P1178 ~25W) CW narrowband (Δυ 22%). We demonstrate our understanding of the arising absorption-induced thermal effects (namely, dephasing and degradation of the conversion), offer predictions towards higher powers and conversion levels, and show that our current results are essentially pump-power limited. We are confident of the scalability of both the IR and visible parts of our system, to these higher output powers and conversion efficiencies.
