The process of refractive index grating formation in a photorefractive crystal, used as the self-adapting spectral filter in an external cavity laser, is studied with a self-consistent model. The model is based on the Finite Difference solution of the Kukhtarev equations. The results obtained are compared with approximate analytical models.
A self-consistent model of a self-organizing external cavity high power laser is presented. The model consists of a photorefractive crystal model, which relies on the plane wave approximation, and of a spectral model of the tapered laser amplifier. The results show that the laser can operate in a single longitudinal mode.
