8.6 ALIGNMENT OF THE BEAM FOLDING UNIT (C2000-E,

C4000-E SHORT OPTICAL PATH LENGTH TYPE)

The beam folding unit has two mirrors. One mirror is fixed, on which

laser beams from the output coupler are reflected first. The other is

movable.

(1) Start the oscillator and make sure that laser beams can be

irradiated.

(2) Attach an acrylic plate at about 3 m away from the beam outlet

of the oscillator, then collect the burn pattern of the CO

gas

laser beam (rated output, CW, irradiation period of 0.1 second).

Do not touch the acrylic plate after beam pattern collection.

(3) Check if the CO

gas laser beam and the guide laser beam are

aligned with each other. If not, make an adjustment according to

Section 8.7.

(4) Adjust the adjustment screw of the beam folding unit so that the

center of the oscillator laser beam matches the center of the

guide laser beam. Do not touch the screws at the support points.

The spacing of support points of the mirror holder is adjusted to

3 mm.
