Tea Laser Emission on the Sequence Bands of CO2,
Abstract
Laser emission on the sequence bands of CO2 has been achieved in a TEA amplifier by using either a hot-CO2 cell or a Michelson interferometer to prevent oscillation of the regular bands. It has been found that the insertion losses of the hot-CO2 filter severely limit the energy-extraction efficiency on the sequence bands. With the Michelson filter, output energies of 140 mJ on the P17 sequence line have been produced in a 33-cm long TEA amplifier. The relatively low efficiencies obtained suggest that the generation of high-intensity laser beams at the sequence-band frequencies would require the use of an oscillator-amplifier combination.
