Abstract

In this paper the realization is described of CO2 laser with high energy (≈10J/pulse), long pulses (≈2μs) and narrow bandwidth (≈200 kHz), using suitable discharge device (Lumonics 602) and cavity configuration (modified self-filtering unstable resonator). The theoretical considerations which led to these choices are also discussed and the results obtained are shown.

Abstract

The design of a CO2 laser system producing single mode microsecond pulses is described. The experimental results obtained on a hybrid oscillator-amplifier system are provided and they exhibit good agreement with the kinetic model developed for the numerical simulation of microsecond pulse propagation. Such a system could be useful for ion-temperature measurements by Thomson scattering on Tokamak plasmas.
