Abstract

The class of nonlinear phenomena based on photorefractive effect in electro-optical crystals plays a vital role in improving the parameters of high power lasers diodes. In optimisation of high power laser diodes both experimental and numerical analysis are very important. The main advantage of numerical modelling is its usefulness to optimisation of device performance in order to meet the target specification. Numerical model allows to simulate scenarios in advance and provides solutions before the investment decisions are made. Moreover, the numerical modelling of photorefractive crystals allows to understand the device characteristics. The main aim of the work was the development of the numerical model for adaptive Fabry-Perot filter using a photorefractive crystal. There were two particular objectives to be reached within this project. The first one was to develop a software tool which allows for calculating the optical field distribution within an optical grating. The second one consisted in combining the developed grating model with an advanced model of the photorefractive crystal based on the solution of Kukhtarev equations. Both objectives have been achieved.
