The MFPT-20H/MFPT-20S (MOPA Pulsed Fiber Lasers) Series products
are characterized by high reliabilty and high performance with the central
emission wavelength of 1060nm. They are high-effecient, air-cooled
and maintenance-free, which make them ideal tools for industrial laser
marking, engraving etc..
Maxphotonics' MFPT-20H/MFPT-20S (MOPA Pulsed Fiber Lasers)
Series are Class 4 laser products and are designed and tested with safety.
By following this User Guide and applying sound laser safety practices, it
will be a safe and reliable device.
Laser light exhibits unique characteristics that may pose safety hazards.
Therefore, the laser light can't be treated as normal light sources, and
all operators and people near the laser must be aware of these special
hazards.
In order to ensure the safe operation and optimal performance of the
product, please follow all warnings and safety instructions in this guide
during process of operation, maintenance and service.
For ensuring the safety of operators, operators are urged not to open
the equipment privately at all times. There are no user serviceable
parts, equipment or assemblies associated with this product. Lasers of
unauthorized disassembly shall not be subject to warranty

Chapter 2 General Safety Information
NOTE :
◎ This device is classified as a high power Class IV laser instrument which
emits light with the wavelength of 1060nm and the optical output power
is up to 20W. This level of light may cause damage to the eye and skin.
Despite the radiation being invisible, the beam may cause irreversible
damage to the retina. Laser safety eyewear is not provided with this
instrument, but must be worn at all times while the laser is operational.
Use appropriate laser safety eyewear when operating this device. The
manufacturer of the laser system is responsible for the safety compliance
according to the applicable standards and regulations.
2-Laser Protection
1.Laser Protection Requirements
You must wear the safety protective glasses while operating the laser,
and rationally select the safety protective glasses according to the lasing
wavelength of the laser. If the device is a tunable laser or Raman product,
it emits light over a range of wavelengths and the end user should confirm
the laser safety eyewear used protects against light emitted by the device
over its entire range of wavelength.
2.Laser Protective Equipment Suppliers
Maxphotonics recommends material or equipments provided by following
laser protective equipment suppliers for you, including LaserVision USA,
Kentek Corporation, Rochwell Laser Industries, etc. All the supplier
information is provided by Maxphotonics only for the convenience to use,
so Maxphotonics assumes no responsibility for any problem caused by
using the products of abovementioned suppliers.

3-General Safety Instructions
In order to ensure the safe operation and optimal performance of the
product, please follow these warnings and cautions in addition to the other
information contained elsewhere in this document.
1.Specular Reflection
There are often numerous secondary laser beams produced at various
angles in the output port of the laser. These divergent beams are produced
when the primary beam of laser reflects off a smooth surface, and they are
called specular reflections. Although these secondary beams may be less
powerful than the total power emitted from the primary beam, the intensity
may be great enough to cause damage to the eyes and skin as well as
surface of materials.
WARNING:
◎ You must exercise caution to avoid/minimize specular reflections as
these laser radiations are invisible!
2.Safety Instructions of Accessories
WARNING:
◎ This device has an output optical head connected to the laser with a
fiber cable. Please be careful dealing with the output head.
3.Optical Operating Instructions
We strongly recommend that you read the following procedures before
operating the laser:
（1）Never look directly into the laser output port when the power is turned on.
（2）Avoid positioning the laser and all optical output components at eye
level.
（3）Ensure that all personal protective equipment is suitable for the
output power and wavelength range of the laser.
