HIGH-PRESSURE AND HIGH-FREQUENCY CARBON DIOXIDE WAVEGUIDE LASER Russian patent published in 2004 - IPC

FIELD: laser engineering; radiation frequency tuned waveguide lasers for medicine, atmosphere monitors, optical radars, target designators, and precision material treatment devices.

SUBSTANCE: proposed CO₂ waveguide laser has cavity incorporating waveguide gas-discharge cell, two mirrors, two diffraction gratings, and magnetostrictive device for displacing one of mirrors along its axis. Diffraction grating functions as first cavity reflector; its second reflector has two interference mirrors whose reflectivity factor is chosen considering requirement of stepless radiation frequency control at particular laser transition.

EFFECT: enlarged lasing spectrum and stepless radiation frequency control area at high cavity selectivity relative to selected radiation frequency.
