Download or read book Gas Re Circulation System for a Miniature High Repetition Rate TEA CO2 Laser written by P. Pace and published by . This book was released on 1976 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: When an atmospheric pressure transverse discharge CO2 laser with forced gas flow is pulsed at a high repetition rate, the minimum time between arc-free discharges is larger than the time predicted by the ratio of discharge width to gas flow velocity. The maximum pulse rate can be predicted by a flow model, the results of which are summarized. The predictions of the model are compared with the experimental results and the design considerations involved in the construction of the gas re-circulation system are presented. (Author).

Download or read book High Repetition Rate Tea CO2 Laser written by M. F. Turgeon and published by . This book was released on 1971 with total page 4 pages. Available in PDF, EPUB and Kindle. 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).
Download or read book A Sealed High Repetition Rate Tea CO2 Laser written by Paul W. Pace and published by . This book was released on 1977 with total page 13 pages. 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.

Download or read book Gas Lasers written by Masamori Endo and published by CRC Press. This book was released on 2018-10-03 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lasers with a gaseous active medium offer high flexibility, wide tunability, and advantages in cost, beam quality, and power scalability. Gas lasers have tended to become overshadowed by the recent popularity and proliferation of semiconductor lasers. As a result of this shift in focus, details on modern developments in gas lasers are difficult to find. In addition, different types of gas lasers have unique properties that are not well-described in other references. Collecting expert contributions from authorities dealing with specific types of lasers, Gas Lasers examines the fundamentals, current research, and applications of this important class of laser. It is important to understand all types of lasers, from solid-state to gaseous, before making a decision for any application. This book fills in the gaps by discussing the definition and properties of gaseous media along with its fluid dynamics, electric excitation circuits, and optical resonators. From this foundation, the discussion launches into the basic physics, characteristics, applications, and current research efforts for specific types of gas lasers: CO lasers, CO2 lasers, HF/DF lasers, excimer lasers, iodine lasers, and metal vapor lasers. The final chapter discusses miscellaneous lasers not covered in the previous chapters. Collecting hard-to-find material into a single, convenient source, Gas Lasers offers an encyclopedic survey that helps you approach new applications with a more complete inventory of laser options.
