Abstract :
A scan laser controlled by the variable reflectance of a VO2film on a CRT faceplate has been demonstrated at 10.6 μm. The cavity is a flat field conjugate resonator with an active medium of axially flowing CO2-N2-He gas mixture. The output beam has been scanned in a circular pattern at 20 Hz. Output modulation has been observed at a raster frame rate of 45 Hz (100 percent) and at a raster line rate of 4.44 kHz (< 100 percent).
