Paper Abstract

A FFT based method is used to calculate the development of electromagnetic (EM) laser field inside a rotating mirror Q-switch laser. The method is applied to study the influence of pumping on the laser pulse temporal evolution and on the near and far field fluence distributions in an "eye-safe" Er: glass laser. Iterative computation of the lowest order modes for the misaligned plano--plano empty resonator shows that for small tilt angles resonator losses depend linearly on the tilt angle. Using linear Q-switching function an analytical expression based on rate equations can be developed which relates the maximum attainable single pulse output energy to the laser parameters. Theoretical results are compared with the characteristics of an "eye-safe" Er: glass laser.
