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.
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 10W～50W.
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 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 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 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.
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.

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:

3) PIN 10、PIN 13 to PIN 15、PIN 24 are all digital GND.
4) PIN 20 is the pulse repeating rate signal (PRR, TTL level). If the PRR need to be changed
during the work, it must be changed 5ms earlier than the EM signal turning into high.

4. Operation Regulations
4.1 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.
4.2 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 preceded.
2) Frequency set introductions
For model P10-20Q, the frequency setting range is from 20 KHz to 60 KHz.
For model P20QE, P30Q,the frequency setting range is from 30 KHz to 60 KHz.
For model P50QB, the frequency setting range is from 50 KHz to 100 KHz.
3) Laser marking checking
For the device initial testing, first turn the power down to zero without turning on the
marking system after the device is successfully started. Then draw a quadrate, marking
continuously while slowly 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
1) Marking frequency must be in the range of 20~60 KHz for P10Q/P20Q, 30~60 KHz for
P20QE/P30Q, 50~100 KHz for P50QB.
2) It should not modulate 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.
