Patara II and Iklwa II Service Manual
a.
Set the laser on a test bench for operation at power level above threshold.
The power should be set at 5 mw.
b.
Install an external 532 nm polarizer cube onto the laser test bench in front
of the output window. Ensure the 532 nm polarizer cube retro reflection is
on axis with the laser beam. Ensure that the 532 nm polarizer cube is
oriented to transmit horizontal polarized light and reject vertical polarized
light.
c.
Loosen the set screw on the top of the waveplate assembly. Using the dial
on the rotation mount, adjust for minimum transmission through the cube.
d.
Tighten the set screw to lock the waveplate location.
