Notizen: Abstract A compact hybrid TEA CO2 laser has been developed which, when operated with the low pressure section well below oscillation threshold, demonstrates that little cw gain is necessary to ensure single longitudinal mode (SLM) output pulses with peak power, energy and pulse shape approaching those of normal multi-mode operation. This has allowed reliable SLM operation to be obtained with a very short, wide bore rf-excited low-pressure section, making feasible simple single-mode, large-aperture TEA lasers with high peak powers and energies.

Notizen: Abstract Negative ions are computed to be formed on a time scale and in quantities such that they may be a cause of plasma instability observed in low pressure electrical discharge convection CO2 lasers. In a typical CO2−N2−He−H2O laser mixture the principal ions are CO 3 − , CO 4 − and H− with the total negative ion densityn − given by 0.1n e 〈n −〈n e , wheren e is the electron density: but if the gases are re-cycled or if there is an air leak NO 2 − and NO 3 − are formed in significant amounts andn − can become greater thann e in a time considerably less than the gas dwell time in the electrical excitation discharge. CO is effective in reducingn − in a system without re-cycling, but is ineffective in a re-cycled system with the oxides of nitrogen present.
