Simple analytical expressions for the optical extraction efficiency from COIL's with different kinds of resonators Academic Article uri icon


  • Abstract It is shown that the celebratex1 Rigrod model (WW Rigrod, J. Appl. Phys., 34, 2602 (1963)) is inadequate for calculating the output power of gas-flow lasers in an important range of parameters where the quenching of the excited species is slow and the optical extraction efficiency is high. For both two level systems and chemical oxygen-iodine lasers (COIL) very simple analytic formulac for the output power are obtained which should be used instead of the Rigrod model. The formulae are given for Fabry-Perot, stable and …
