a. The maximum power levels specified here are for the feedback electronics, but the maximum
input power at these settings is limited by the damage threshold of the liquid crystal retarder,
which is 8 W/cm
2
. See the section 5.2, Max Powers at Various Wavelengths, for details.
b. This setting is not recommended. If used, do not exceed the power level for the H – 3 setting.
