Available in PDF, EPUB and Kindle. Book excerpt: A compact atmospheric pressure CO2 laser utilizing a double-discharge technique has been constructed and operated at moderate repetition rates. With the addition of small amounts of hydrogen and carbon monoxide to the He-CO2-N2 gas mixture, sealed operational lifetimes exceeding 2 x ten to the 6th power pulses have been obtained. Operating in this mode, the output energy is about 250 mJ/pulse at repetition frequencies of 40-50 pulses/s.

This book was released on 1977 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The envelope and frequency characteristics of the output pulse of a high-repetition-rate hybrid TEA-CO2 laser are presented. Both the intrapulse and interpulse laser frequency stability are experimentally determined at repetition rates up to 300 Hz. The recovery of the CW laser signal following the generation of the TEA laser pulse is analyzed theoretically and experimentally. Short term reproducibilities of + or - 2 MHz are observed at a pulse repetition rate of 300 Hz with initial chirp rates of about 1.5 MHz/microsec. Improvements and limits on power and repetition rate are discussed. (Author).

Book excerpt: This correspondence reports on the successful operation of a TEA CO2 laser at rates up to 1000 pps with an average output power up to 65 W over long periods of time. An essential feature of the present system is a rapid gas circulation transverse to the laser axis combined with a large volume of ambient gas. It is found that decomposition of the gas is one of the major problems at high repetition rates. (Author).

Book excerpt: A compact, sealed, TEA-CO2 laser utilizing a double-discharge technique has been constructed and operated under single-mode conditions. Sealed operational lifetimes exceeding 1,000,000 pulses have been obtained by the addition of small quantities of hydrogen and CO to the initial gas mixtures. It has also been found that operation without helium is possible giving single-mode output energies of about 35 mJ/pulse at peak powers of about 150 kW. The pulse repetition frequency was 0.5/s. To obtain single-longitudinal-mode operation, the laser cavity was kept at on overall length of 18 cm. This short laser cavity allowed the oscillation of only one longitudinal mode when the frequency of the cavity was tuned closely to the CO2 line centre frequency. An iris was used to restrict transverse modes to the TEM. Beat frequency measurements using a stable, CW CO2 laser indicate a chirp of about 5-6 MHz/microsec in the tail of the pulse. (Author).
