1.1 Principles of a Fiber Laser
LASER is the acronym for Light Amplification by Stimulated Emission of Radiation. A fiber laser is a laser in
which the active gain medium is an optical fiber doped with rare-earth elements such as
erbium, ytterbium, neodymium, dysprosium, praseodymium, and thulium. They are related to doped fiber
amplifiers, which provide light amplification without lasing. GCC fiber laser utilizes a MOPA technique used to
achieve a pulsing laser, it can generate pulse width in the nanosecond range. A short pulse width generates
an extremely high peak power. Such high peak power is very potent and effective in marking of metallic
objects or other hard processed material. The advantages of fiber laser source is compact, high quality
optical beam, energy efficient and no consumables. The laser beam delivery in terms of beam size and laser
power are very consistent due to the good reflective nature and efficient cooling capacity of the fiber laser.
1.2 Safety Ratings
The LaserPro S290LS is equipped with a DPSS laser that emits intense and invisible laser radiation with a
wavelength of 1 micron in the infrared spectrum. The laser system is designated as a Class I laser device,
meaning that the system is equipped with key safety features and an enclosed laser head to completely
contain the laser under normal use. One of the key safety features found on the LaserPro S290LS is
a Class 3R red dot safety guidance pointer (similar to a laser-pointer presentation pen) allowing the
operator to see the exact location where the laser beam will fire. Even though the LaserPro S290LS
is equipped with the most powerful laser to date, through proper usage and taking necessary hardware
safeguards, will make it an extremely safe machine. When the front door and back door are open, machine
becomes a Class 4 equipment and users must wear goggles to operate the machine.
1.3 The Safety Interlock System
The laser system is equipped with a safety interlock system utilizing magnetic sensors on the top and
side access doors, laser-activation and door LED lights on the control panel. The magnetic sensors will
deactivate the laser when either door is opened. At this time, the “door” LED light found on the control
panel will illuminate, indicating an open or improperly closed door. When the laser is in operation, the “laser”
LED will illuminate to inform the operator that the laser is activated. If at any time, any of the access doors
are open and the “laser” LED is illuminated, IMMEDIATELY unplug the laser system and contact GCC
service team for technical support and maintenance instructions.
WARNING
࣭
DO NOT operate the laser system if any component of the safety system is malfunctioning.
࣭
DO NOT attempt to remove or modify any component of the safety interlock system.
1.4 Safety Labels
According to CDRH standards, all fixed or removable covers that allow access to a laser beam must have
appropriate laser warning labels attached to them. These warning labels must be clearly visible to the
operator prior to removing the cover. Additional labels must be applied to the interior of the machine and
be visible in the event when the covers are removed. A label clearly displaying the manufacturer’s name,
