Modeling of lasing in COIL's with stable resonators Academic Article uri icon


  • Abstract A model is developed describing the power extraction in COILs with stable resonators when a large number of transverse Hermite-Gaussian eigenmodes oscillate. The extraction efficiency, mode intensities and intensity distribution along the flow depend only on two parameters. The first is the ratio YO f the residence time of the gas in the resonator to the O2 (A) energy extraction time and the second is the ratio of the threshold to the small signal gain. The efficiency is maximum for Yo~", and decreases very fast as YQ …
