Laser intensity measurement
At first, maximize each laser intensity. Move off all of movable ND filters from the optical path and
adjust Argon laser to its maximum power. Measure and record the light intensity of each laser emitting
from the coupler with a calibrated laser intensity power meter.
This completes the rough setup of the lasers.
