Abstract
Application of radio frequency excitation to transverse flow CO laser has led to the successful realization of high output-high-power high-conversion-efficiency oscillation at room temperature. The operating performance of the laser system thus developed has been examined in such aspects as the effects brought by changes in the laser operating parameters on the discharge and laser output characteristics, and on the beam profile. In experiments performed to date, an output power of 992 W at a conversion efficiency of 15% has been achieved with a gas temperature of 286 K, using gas made up of He, N2, CO and O2, without Xe addition. Compared with operation at cryogenic temperature, room temperature operation has proved to ensure more stable and more uniform excitation over the entire discharge space, and to permit extraction a beam of distinctly higher quality, thus demonstrating the superiority of room temperature operation.
