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.
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 24VDC power source is
connected and the anode and cathode are right. Failure to connect power source correctly will
cause damage to the device.
The device emits invisible 1060~1085nm wavelength light with average power 20W/30W. 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 look into the light output end directly. Use appropriate laser safety eyewear when
operating the device.
Safety labels and locations
The two labels above are located on the top of the cover of the device, representing laser
radicalization.

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.
(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. 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.
(3) 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.
(4) If the operating the device fails to follow this instruction, the protective function will be

weakened. Therefore, it should be used under normal conditions.
(5) Do not install the collimating device into the output head when the laser device is in working.
(6) 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.
(7) 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.
(8) Make sure the pulse repetition rate higher than 20 kHz.
(9) 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.
(10) Power source sudden interruption will do great harm to the laser device. Please make sure
the power supply works continuously.

2.1 Mounting dimensions
(1) Fiber Laser module dimensions (As shown in Fig. 1).
Figure 1. Dimension drawing of laser module (Unit: mm).
(2) Isolated output isolator (As shown in Fig. 2).
Figure 2. Dimension drawing of output isolator (Unit: mm).
2.2 Method of installation
(1) 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.
(2) Fix the laser device steady on the holder and ensure good ventilation.
(3) 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.

(4) Pin A1 & A2 are the positive and negative power line connector to the control board.
Pin 2 & A2 are the positive and negative power line connector to the laser driver.
During the operation, all the power connectors must be correctly connected, or laser
wouldn’t operate. Depending on the specific requirements in actual operation, the
control board and laser drive can be powered together or separately.
(5) During the operation, disconnection of any connect wire will lead the disable of laser
emission
(6) Make sure the control connector of external controller is compatible with the laser
device. Fix the control wire steady onto the laser control connector.

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 Fig. 5.

(1) 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:
