Make a horizontal adjustment to the HM mount. Recover the laser
power by making a similar adjustment to the horizontal control of
the HR mount. Check and adjust the temperature of SHG crystal.
Continue if improvement is noted. If there is no improvement, try
the opposite direction.
Perform the same procedure with the vertical adjustments of the
HM and HR mount.
Typically, SHG temperature adjustment is not needed when
adjusting vertically. Periodically check for hold off when making
these adjustments (see in the
Check Hold Off
section in
Chapter 5:
Maintenance
).
If laser power is /-5 percent of nominal (typical power
meter accuracy), and it has good beam shape and stability, stop and
replace the access screws in the cover.
