Safety Overview

Precautions for Safe Operation

© 2018 Cutting Edge Optronics, Inc.
Safe operation of any laser should be reviewed prior to any new installation of the
Patara laser.
CAUTION.
The Patara laser is a Class IV, high power laser whose beam is, by
definition, a safety hazard. Avoid eye or skin exposure to direct or scattered laser
radiation. Avoid direct viewing of the beam or its specular reflection.
Follow the instructions contained in this manual for proper installation and safe
operation of the laser. Use of protective eyewear is recommended at all times (the type
of eyewear depends on the energy and wavelength of the laser beam and operating
conditions). Consult ANSI, ACGIH, or OSHA standards for guidance.
CAUTION.
Use of controls, adjustments or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
WARNING.
At all times during installation, operation, maintenance, or service of the
laser, avoid exposure to laser or collateral radiation exceeding the accessible emission
limits listed in "Performance Standards for Laser Products," U.S. Code of Federal
Regulations, 21 CFR 1040 10(d).
 Avoid looking directly into the laser beam or at specular reflection, even with
protective eyewear 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.
