- 論文の詳細を見る
A novel optical method of temperature measurement was used to analyze a slab-type 40 MHz RF discharge excited CO2 laser plasma active medium. The method was based on near-infrared absorption spectroscopy with a 1.6 μm distributed-feedback (DFB) semiconductor laser. Gas temperatures from 450 to 650 K were measured at pressures of 1 to 6 kPa with discharge electrode distances of 5.0 and 7.5 mm. This method may provide a practical sensor for the real-time diagnostics of the active medium of CO2 lasers.
