Study on a compact and long-life RF excited waveguide CO2 laser

  • Received Date: 2009-04-29
    Accepted Date: 2009-07-01
  • In order to have more comprehensive application in industry and military fields,a compact and long-life radio frequency(RF) excited waveguide CO2 laser was developed by means of Al-alloy laser housing,plat inductor coils instead of traditional rolling inductor,all-metal-sealed techniques and etc.The specifications of this laser are continuous or pulse output up to 20kHz modulating frequency,average laser output power up to 30W,over 1500h of working time and 1.5a of storage time.The results show that this laser has the characteristics of compact structure,steady output power,long life,continuous and pulse working-mode.It can be used both in industry and military fields.

Abstract: In order to have more comprehensive application in industry and military fields,a compact and long-life radio frequency(RF) excited waveguide CO2 laser was developed by means of Al-alloy laser housing,plat inductor coils instead of traditional rolling inductor,all-metal-sealed techniques and etc.The specifications of this laser are continuous or pulse output up to 20kHz modulating frequency,average laser output power up to 30W,over 1500h of working time and 1.5a of storage time.The results show that this laser has the characteristics of compact structure,steady output power,long life,continuous and pulse working-mode.It can be used both in industry and military fields.
