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.
 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
damage the device.
 The device emits invisible light with a wavelength from

1060nm to

1085nm
with average power of 200W. Do not expose your eyes or skin to the radiation of the
laser.
 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.
 Do not directly look into the fiber delivery cable connector. Use appropriate laser safety
eye-wear(i.e. laser goggles) when operating the device.

1. Product 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 low-volume consumption,
suitable for laboratory or outdoor operation, compact, can be placed independently, 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 and the output power of the power
supply needs to be greater than 1000W.
1.2. Actual configuration list
The list of the actual factory configurations of the laser is shown in Table 1.

1.3. Environmental requirements and cautions
Pulsed laser should be driven by 24V DC±1V power source. The power output of the power supply is
above 1000W.
1. Caution: Make sure the corresponding wires of the device are properly grounded.
2. All the maintenance to the device should only be done by Raycus because there is no
replacement or accessory provided with the device. To prevent against electric shock
Please do not try to damage the labels or open the cover, or the warranty will be invalid.
3. The fiber delivery cable connector of the product is connected with an optical cable.
Please be careful when handling the fiber delivery cable connector. Avoid dirt and any
other contamination. Please use the specialized lens paper when cleaning the lens.
When the laser is not installed on the system equipment and does not produce light,
please cover the optical isolator protective cover to avoid dust contamination.
4. If the laser is not used as specified in this instruction manual, the protective
function it produces will be weakened. Therefore, the product must be used in a
normal environment.

5. When the laser is in operation, it is strictly prohibited to install the output collimator.
6. The laser has seven fans at the tail plate for heat dissipation, which must ensure
sufficient airflow for heat dissipation. The laser fan works in a blowing direction, i.e.
the direction of airflow is from the fan position to the laser fiber delivery cable
connector position. At least 10 cm of ventilation space is left in front and behind the
laser. If the laser is installed in a cabinet with its own cooling fan, it must be ensured
that the cabinet fan airflow direction is not opposite to the laser airflow direction.
7. Do not look directly at the fiber delivery cable connector, in the operation of the
machine to ensure long-term wear to prevent 1μm wavelength laser protective eye
environment.
8. Maximum use time without pulse is 50 x 10-6seconds.

1. 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.

3. Pin 17 is a 5V input voltage, which is used to supply power to the internal isolated optocoupler
of DB25 interface, and the input current is more than 20 mA.
4. Laser external input signals (pins 1-8,18,19,20,22) are connected to the optocoupler inside the
system to ensure that the input level is digital high in the range of 3.3V-5V, and digital low
below 1.7V.
5. The laser alarm output signal (pin 11,16,21) is connected to the optocoupler inside the system,
and it is necessary to ensure that pin 17 has provided 5V power supply to get a valid signal.

3.2. Pre-inspection
1. Make sure the device appearance is in good condition and the output fiber is neither
excessively bended nor broken.
2. Make sure signal line of laser and marking system are properly connected.
3.3. Operation procedures
1. Starting procedures
Please make sure the control system is on before you turn on the fiber laser. Only after
at least 1 minute since the power turned on, the subsequent operations can be proceeded.
2. The frequency setting range is from 1 kHz to 4000 kHz(The actual frequency range of
each pulse width is showed in the Table 3).
3. The operation steps of laser marking after the marking machine is turned on checks
For the device initial testing, first turn the power down to 10% without turning on the
marking system after the device is successfully started. Then draw a quadrate,
marking continuously while slowly increasing the power from 10% to 100% at the
same time. Meanwhile, use a ceramic material to observe the laser and the laser
should become stronger, otherwise shut down the device and check. If operating
normally, the marking system can be used in common order afterwards.
3.4. Cautions
1. Marking frequency must be in the range of 1 kHz to 4000 kHz(The actual frequency
range of each pulse duration is showed in the Table 3).
2. Do not modify the frequency while marking.
3. Stop marking first before shutting down the device, then turn the power down to zero
and cut the power off.
