Safety Information
Please read this instruction carefully and familiarize yourself with the information we have
provided before you use the product. In this brochure, important operation procedures, safety and
other information are provided for you and all future users. In order to ensure operating safely
and optimal performance of the product, please act according to following warnings, cautions
and other information.
a) Raycus pulsed fiber laser is classified as a high power Class IV laser device. Before
supplying the power to the device, please make sure that the correct voltage of 24V DC
is connected and the anode and cathode are right. Incorrect polarity or voltage will
harm severely the device.

b) The device emits invisible light with a wavelength from
 
1060nm to
 
1085nm
with average power of 70W. Do not expose your eyes or skin to the radiation of the
laser.
c) Do not take apart the device, because there are no replaceable accessories available for
users to use. Any maintenance can only be proceeded in Raycus.
d) Do not look into the light output end directly. Use appropriate laser safety eye-wear(i.e.
laser goggles) when operating the device.
Safety labels and locations

1. Description
1.1. Product description
Raycus pulsed lasers are specially developed for high-speed and efficient laser marking
systems. For industrial laser marking machine and other applications provide an ideal high-power
laser energy source.
Compared with traditional laser，pulsed laser can increase the conversion efficiency of
pump light per watt by more than 10 times. Automatic design for high-volume consumption,
suitable for laboratory or outdoor operation, compact, can be placed independent, can be used at
any time, can be directly embedded on the user’s device.
The device can emit 1060~1085nm wavelength pulsed light under the control of industrial
laser’s standard interface driven by 24V DC power source.
1.2. Actual configuration list
Please refer to the included list according to Table 1.

1.3. Environmental requirements and cautions
Pulsed laser should be driven by 24V DC±1V power source.
a) Caution: Make sure the corresponding wires of the device are properly grounded.
b) All the maintenance to the device should only be done by Raycus, because there is no
replacement or accessory provided with the device. Please do not try to damage the
labels or open the cover in order to prevent against electric shock, or the warranty will
be invalid.
c) The output head of the product is connected with an optical cable. Please be careful
handling the output head. Avoid dirt and any other contamination. Please use the
specialized lens paper when cleaning the lens. Please lid the laser with protective cover
of the light isolator to be against dirt only when the laser is not installed in the device or
not in working.
d) If the operating the device fails to follow this instruction, the protective function will be
weakened. Therefore, it should be used under normal conditions.
e) Do not install the collimating device into the output head when the laser device is in
working.

f) The device has four cooling fans at the rear panel to dissipate heat. In order to
guarantee enough airflow to help giving heat off, there must be a space of at least 10
cm’s width for airflow in front and rear side of the device. As the cooling fans are
working at blow condition, if laser is mounted in a cabinet with fans, the direction
should be same as laser’s fans.
g) Do not look into the output head of the device directly. Please do wear appropriate laser
safety eyewear during operation of the device.
h) The longest time without pulse is only 100
s 
. If there is no pulse output, please stop
marking at once to avoid the further damage of the device.
i) Power source sudden interruption will do great harm to the laser device. Please make
sure the power supply works continuously.

3. Control Interface
There are DB9 and DB25 interfaces at the rear of the laser. The DB9 is a RS232 interface
only used for debugging, no needs to connect. And DB25 is the joint interface connecting control
system to the laser system, please make sure the connection is reliable before operation. Feet of
the DB25 are defined as follows in Table 4.

a) The pump current of the diode laser and the laser output power are controlled by setting
the value of Pin1-Pin8 (TTL level). Pin1-Pin8 can be set from 0 to 255，corresponding
to the laser output power from 0 to 100％(the actual laser power may not be strictly
linear with the setting value). The relationship between Pin value and output power is
shown in Table 5.
b) Pin 10 and Pin 14are all digital GND.
