3.1 OUTLINE
Fig. 3.1 show the internal structure of the laser oscillator.
The C1000iA consists of a laser resonator, discharge drive unit,
forced gas circulating system, pressure controller, CNC interface, and
a protective housing.

(1) Laser resonator
The laser resonator consists of several discharge tubes,
connected in series using folding mirrors, with a rear mirror and
output mirror placed at the open ends of the discharge tubes, thus
sealing the tubes. The resonator is fitted with a gas pipe
connecting port through which laser gas is fed into the discharge
tubes.
A discharge from the electrodes of the discharge tube energizes
CO

molecules, which emit light. This light is amplified by
stimulated emission, repeated between the rear mirror and output
mirror, a laser beam being emitted from the output mirror.
