Near Field/Far Field (NF/FF) Energy Loss in Electric Discharge Lasers (EDL's): A Mode-Medium Interaction.

Abstract

High energy CO2 EDL's (Electric Discharge Lasers) with unstable resonators exhibit a mode-medium interaction which spreads the focussed beam and causes loss in the far-field. Mirror edge Fresnelling may result in amplified feedback which causes a parallel-piped structure to be burned into the lasing medium. Possible confirming experiments are described. (Author)
