Precautions for Safe Operation
Avoid looking directly into the laser beam or at specular reflection, even with
protective eye wear on.
Wear laser safety eyewear that is optically dense at the wavelengths of
operation (798-816 nm pump light, 1064 nm fundamental, 532 nm second
harmonic).
Provide a controlled access area for laser operation and limit access to those
trained in laser safety principles.
Post warning signs in prominent locations near the laser operation area.
Use safety interlocks on all entryways. All Northrop Grumman system control
electronics are supplied with interlock inputs that can be used to preclude
operation with an open safety door.
Enclose beam paths wherever possible.
Set up experiments so the laser beam is below eye level.
Work in an area that is well lighted to avoid dilation of pupils.
Set up a target for the beam.
Set up shields to prevent reflected beams from escaping the laser operation
area.
View an infrared laser beam with a protected image converter at an oblique
angle reflecting from a diffuse surface.
Ensure that all electrical connections are made in a safe manner.
Position equipment so that electrical connections are shielded from accidental
touch.
Do not smoke, eat, or drink in laser areas.
Avoid leaving an operating laser unattended.
