Abstract
By replacing the conventional (non line-selective) unstable resonator, we succeeded in developing the very high power line-selective (line-tunable) CO2 laser as a pumping source for high power molecular gas (e.g.NH3) lasers in the infrared and far-infrared regions.
The experiments were performed by using the very high power CO2 laser (4A unit of Lekko VIII) at The Institute of Laser Engineering, Osaka University.
The output power of 9R(30)9.22µ m line from the developed CO2 laser, for instance, exceeded 0.5GW/pulse (50J/pulse with pulse width of 100nsec).
