Electric field effects on an optically-pumped HCOOH FIR laser and Zeeman laser theory
Abstract
Electric field effects have been investigated on the output power of six far-infrared (FIR) laser lines from H12COOH optically-pumped by a CO2 laser with its polarization arranged perpendicular to the Stark field. Optoacoustic signals observed on the pump lines were hardly affected by the applied electric field up to 0.6 kV/cm. By neglecting the electric field effects on the pump transitions, Zeeman laser theory has been applied to the FIR laser transitions. Numerical calculation predicts the observed FIR output power as a function of electric field. Experessions for oscillation frequency and intensity in homogeneous limit are given, which may be applicable to any FIR Stark laser so far as the pump transition is free from electric field effects.
