To increase output power of a He-Ne laser we propose to use the capacitive rf discharge and implement four channel structure. Most of experiments were carried out with a single laser tube from this structure to optimize the output mirror transmission

Four-channel structures in form of the second rank 2x2 matrix were investigated. For CO2 lasers we applied phase-locking techniques. He-Ne and He-Xe lasers were built as independent four-channels and optimized for their output power.© (2003) COPYRIG
