Waveguide CO₂laser with multiply folded resonator

摘要

A gas-discharge waveguide CO2 laser has a Z-shaped folded waveguide formed by three ceramic tubes. Ends of the adjacent tubes are shaped and fitted together to form a common aperture. The tubes are held fitted together by spaced-apart parallel discharge electrodes. Four minors are arranged to form a laser-resonator having a longitudinal axis extending through the tubes.

主权项

1. A gas discharge laser, comprising:
a laser housing including a lasing gas; a plurality of independent dielectric waveguide tubes located in the laser housing and filled with the lasing gas, with adjacent ones of the dielectric tubes thereof at an acute angle to each other, and with ends of the adjacent ones thereof being cut to define a taper and fitted together to form a common aperture; first and second electrodes located in the housing and arranged to create a gas discharge in the lasing gas in the dielectric tubes when electrical power is applied to the electrodes; and a plurality of mirrors arranged to form a laser-resonator having a longitudinal axis extending through the plurality of dielectric tubes.
