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 operatingsafely
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.

1. Description
1.1. Product description
Raycus P20QB/P30QB pulsed fiber 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 24VDC power source.

1.3. Environmental requirements and cautions
Pulsed laser should be driven by 24VDC±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 100 us. If there is no pulse output, please stop
marking 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.

b) Isolated output isolator (As shown in Fig. 2).
Figure 2. Dimension drawing of output isolator (Unit: mm).
2.2 Method of installation
a) The laser output fiber is the key but very sensitive component. During the package,
transport and operation, the bending radius of output fiber must not exceed 15 cm, or
the laser may be damaged. The leading and tail parts of the output fiber must not be
excessively bended, in case of damaging. When returning the laser for warranty, it
suggests using the original package. If the original package is not accessible, the laser
device and output isolator must be packed with suitable soft materials in case of

damaging due to vibration during the transportation.
b) Fix the laser device steady on the holder and ensure good ventilation.
c) The power connector of this high performance small volume laser device is DB7 dual
power supply. Connect the power line to the 24V DC power supply and ensure
sufficient output power. Notice the polarity of the power line.

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 Fig. 5.

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

signal must be switched ON, in other word, the signal of PIN 18 must be ahead of PIN
19 at least 5 ms, and otherwise the laser machine may be damaged.
f) I/O connection of digital signal: the supply current of inputsignals are less than 10mA,
and the supply current of outputsignals are less than 3 mA . The connection circuit of
input/output signals is shown in Figure 6.
Figure 5.Schematic of input and output signals.
g) The control board and laser driver can be powered separately. When there is failure in
24V control board power supply, the laser will stop emission after 20 ms. When there
is failure in 24V laser driver power supply, the laser will stop emission after 4 ms.
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 this special laser device, the frequency setting range is from 20 kHz to 60 kHz
(P20QB), or from 30 kHz to 60 kHz (P30QB).
c) Laser marking checking
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 0% 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 of 20 kHz～60 kHz (P20QB), or 30 kHz～
60kHz (P30QB).
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.
