Abstract
Measurements of the optical beam quality of the 3.2 micron output of the Stanford Super-conducting FEL are reported. Profiles of the far field focus are presented in both time average and single shot cases. The results differ by less than 10% from the predictions for an ideal Gaussian beam. Also presented are measurements of the near field profile and the Rayleigh range.Keywords
