A study of the stability of a high-power free electron laser utilizing a short Rayleigh length Conference Paper uri icon


  • In order to avoid mirror damage on a high-power free electron laser (FEL), the design can utilize a short Rayleigh length optical cavity in combination with a short magnetic undulator. The short Rayleigh length increases the mode area and reduces the intensity at the mirrors, and also alters the basic FEL interaction and the stability of the laser itself. In particular, mirror misalignment may significantly affect the behavior of the cavity modes. We present simulations showing the effect of mirror tilt on the performance of 100 kW and 1 MW FEL designs with short Rayleigh lengths. 2003 Elsevier Science B.V. All rights reserved.
