Download or read book Continuously Tunable High Repetition Rate RF Excited CO2 Waveguide Laser written by Stian Loevold and published by . This book was released on 1982 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of pumping a CO2 laser with a radiofrequency discharge at multiatmospheric pressures in order to obtain continuous frequency tuning has been investigated both theoretically and experimentally. Experimentally 40.68 MHz rf-excitation of discharges between parallel plate electrodes with up to 7-8 kW peak rf-power has been investigated. Emphasis has been laid on how to attain a stable glow-discharge with sufficiently long duration before arcing for integration of enough rf-power in the discharge to reach threshold for laser oscillation. A 10 atm rf-excited CO2 waveguide laser has been developed. With no dispersive elements in the laser resonator and with a 2% output coupler, input rf-power threshold for laser oscillation was 2 kW at 10 atm. Peak output power was 1.5 kW for 7-8 kW input rf-power. The output pulse has the form of a 300 ns duration gain-switched pulse followed by a tail at lower power. An efficiency (input rf-energy/laser output-energy) of 2% has been measured for the gain-switched pulse. The laser has been operated with pulse repetition rates in excess of 1 kHz, limited primarily by the available gas-flow capacity. Continuous frequency tuning between the R(12) and R(14) lines in the 10.4-micrometer band has been demonstrated. (Author).

Download or read book Gas Flow and Chemical Lasers written by Salman Rosenwaks and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sixth International Symposium on Gas Flow and Chemical Lasers (GCL) was held in Jerusalem, Israel, on September 8-12, 1986. The charm and beauty of Jerusalem and the unique blending of ancient and modern made this Symposium an enjoyable experience for the 165 participants and the accompanying persons. Yet, it seems that the invited and contributed papers presented at the Symposium were equally attractive so that most of the participants attended most sessions, resisting the temptations outside the session hall. Indeed, many speakers presented up-to-date results that were obtained, or cleared, just a few days before the Symposium. This volume is a compi lation of 19 invited and 61 contributed papers and of a panel discussion on the prospects for short wavelength chemical lasers held at the closing session of the Symposium. This discussion is presented as recorded in order to re tain the flavour of spontaneous presentation at the risk - or advantage - of presenting some venturous ideas, and the danger of misquoting. In editing the book, a deductive approach has been attempted. The book starts with some fundamental issues, namely fluid dynamics and optics, and then deals with the design, diagnostics, propagation and applications of various gas laser systems, covering the wavelength spectrum from XUV to infrared. Then follow recent developments of general interest to the laser community and the book concludes with an eye to the future, i.e., with a section on short wavelength chemical lasers.
