Safety

Precautions for Safe Operation of Class IV Lasers
© 2016 Cutting Edge Optronics
Some repair and diagnostic procedures require the opening of the laser while the
system is running. Wear the correct eye protection and also be careful of electrical
hazards. The laser system has been designed to minimize the risk, but still be
cautious and conscious of your and others safety.
 Never look directly into the laser beam or at specular reflection, even with
protective eye-wear on.
 Always wear laser safety eye-wear that is appropriate for the output power at
the wavelengths of operation (532 nm, 808 nm and 1064 nm).
 Set aside a controlled-access area for laser operation; limit access to those
trained in the principles of laser safety.
 Post readily readable warning signs in prominent locations near the laser
operation area.
 Use safety interlocks on all entryways. All NG system control electronics are
provided with interlock inputs to preclude operation with an open safety door.
NOTE: when multiple interlocks are used, they must be connected in SERIES
for proper function.
 Restrict access to laser areas to those who have been instructed in the
necessary safety precautions.
 Enclose beam paths wherever possible.
 Set up experiments so the laser beam is below eye level.
 Work in an area that is well lit 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.
 The Q-switched output power of the laser emits extremely high peak optical
powers, powers that can severely damage a wide array of optical components
