Abstract
The continuous-wave operation of a self-adaptive laser which oscillates by diffraction from a gain hologram is modelled numerically. We demonstrate the greater-than-unity diffraction efficiency of a single gain grating and show how the properties of an externally-written gain grating laser lead to the realization of an entirely self-starting system. The dependence of output power on parameters such as intracavity gain and output coupler reflectivity is investigated, thereby enabling the optimisation of power extraction and improving understanding of steady-state holographic laser action.
