Amplified Spontaneous Emission(ASE) negatively effects the performance of some oscillators or amplifiers. Some laser models use numerical multi-element approaches. This approach complicates the computation of the ASE significantly.
The three dimensional discrete Radon transform is proposed as a numerical method to compute the integral which describes the ASE radiation. The simulation shows that the use of discrete Radon transform algorithm(s) reduces the computational cost of the ASE integral in some cases. Other properties such as invertiblity and geometric accuracy of the Radon transform are investigated.
Simulation of the ASE output of a end pumped Ho:YLF gain medium was performed using both a direct integration and the Radon transform method. The results of the simulation show the saturation behaviour and the wavelength dependence on geometry of the system.
