Green Diode-Pumped Solid-State Laser Systems (Hardware)

For Your Safety
technician. There are no user-serviceable parts or controls inside the
protective housings of the laser or power supply, and the laser system
must never be operated with the covers removed.
The laser power supply contains circuits that operate at high voltage.
THESE VOLTAGES CAN BE LETHAL. Refer any service
requiring access to the inside of the laser head or power supply to
your nearest Melles Griot authorized representative.
• DO NOT disconnect the protective ground terminal on the power
supply ac line cord.
• DO NOT use a grounding adapter to plug the power supply into a twowire
outlet. Have a grounded three-wire outlet installed by a qualified
electrician.
• DO NOT attempt to defeat the interlocks (see Laser Emission Control
Devices in Appendix D).
• ALWAYS disconnect the power to the power supply before
connecting or disconnecting the cables between the laser head and the
power supply.
1.3 Laser Safety
Laser light can be hazardous if it comes in contact with the skin or the eye,
causing burns, eye damage, and even blindness. The 58 Series laser
systems described in this manual are designed solely for use by OEM
manufacturers that are incorporating the lasers into equipment for resale.
As such, they are not required to meet all of the safety and labeling
requirements set forth in CDRH regulations 21 CFR 1040.10 and
European norm EN 60825-1:1994. Nevertheless, all of the electrical
requirements of these regulations (e.g., key switches, warning lights,
interlocks, and time delays) are built into the systems and are easily
accessible to the OEM manufacturer. Unless especially equipped, the
lasers do not include the laser output shutter and compliance labels
required of end-user Class IV (Class 4) laser systems.
The 58 Series green DPSS lasers are classified as CDRH Class IV/IEC
Class 4 devices, indicating that they are considered to be an acute hazard
to the skin and eyes from direct and scattered radiation. This class of laser
can also be a fire hazard if not used properly.
Never look into the laser beam, with or without appropriate safety
goggles. Permanent eye damage or blindness will result!
Keep all parts of the body and reflective materials out of the beam path as
well.
