Description
Summary:A method is described for calculating the radial distribution of the absorbed power density inside the dye solution of a flashlamp-pumped dye laser. The calculation takes into account both the geometrical parameters (diameter of the dye tube, wall thickness) and the relevant physical parameters, such as the indices of refraction of the tube material and the dye solution, dye concentration, absorption spectrum of the dye, and emission spectrum of the flash. The calculation is based on the Monte Carlo method and is particularly suitable for machine computations. After a detailed description of the method of calculation, it is demonstrated for the practical case of the dye Rhodamine 6G dissolved in ethanol. Some of the absorption profiles thus obtained are compared with fluorescence profiles measured by Gassman and Weber (1971).
