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 do 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 power source is connected and the anode and cathode are right. Failure to connect
power source correctly will cause damage to the device.

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 eyewear
when operating the device.
Safety labels and locations
The two labels above is located on the top of the cover of the device, representing laser
radicalization.

1.Description
1.1. Product description
Raycus pulsed laser is an ideal high power laser source with high speed and high efficiency.
It is specially designed for industrial laser making system and other applications.
Compared with traditional lasers, pulsed laser has some unique advantages in increasing the
conversion efficiency of the pump light 10 times higher.Its low power consumption and
automotive design make it appropriate for operating both in and outside the lab. Besides, it is
exquisite and convenient for its independence in placement, free time in using and facility in
connecting to equipment directly.
The device can emit 1060~1085nm wavelength pulsed light under the control of industrial
laser’s standard interface driven by 24V DC power source.

1.3. 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 contaminations. 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 three 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
10cm’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 the time when operating the device.
h) Make sure the pulse repetition rate higher than 20kHz.
i) For the longest time without pulse is only 50 x 10-6s. If there is no pulse output, please
stopmarking at once, to avoid further damage of the device.
j) Power source sudden interruption will do great harm to the laser device. Please make
sure the power supply works continuously.

Obligate PIN
Reserved for Raycus only
a) The pump current of diode laser and the laser output power are controlled by setting
the value of PIN1-PIN8 (TTL level). PIN1-PIN8 can be set from 0～255，
corresponding to the laser output power from 0～100％(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 4:
b) PIN 10,13,14,15,24,25 are all digital GND.
c) PIN 17 is the external 5V DC input, providing power for inside chips of alarm signal to
ensure that alarm signals are valid.
d) PIN 18 is the start signal of the MO. PIN19 is the input for the optical output signal.
The electrical level for both PIN18 and PIN19 are 5V. Before turning on PIN 19, MO
signal must be switched ON, in other word, the signal of PIN 18 must be ahead of PIN

4.Operation Regulations
4.1 Pre-inspection
a) Make sure the device appearance is in good condition and the output fiber is
neitherexcessively bended nor broken.
b) Make sure signal line of laser and marking system are properly connected.
4.2 Operation procedures
a) 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 preceded.
b) Frequency set introductions
For modelP20Q, the frequency setting range is from 20kHz to 60kHz.
c) Laser marking checking
d) For the device initial testing, firstturn the power down to zero without turning on the
marking system after the device is successfully started. Then draw a quadrate, marking
continuously whileslowly increasing the power from zero 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.
4.3 Cautions
a) Marking frequency must be in the range of20~60 kHz.

b) It should not modulate the frequency while marking.
c) Stop marking first before shutting down the device, then turn the power down to zero
and cut the power off.
