Safety
Please read this user manual carefully before operating the YDFLP fiber laser. It provides
essential information regarding safety, product operation, and other necessary reference
information. For the purpose of safety operation and maximizing the performance of the fiber
laser, please strictly follow the safety notifications as below:
●Make sure the +24VDC power supply is connected in the correct way. Inappropriate
connection might spoil the product.
●You can’t open the cover of this product without the permission of JPT. It might cause
safety issues and invalidate the warranty.
●Please wear laser goggle, as shown in Fig. 1, all the time during the operation. This laser
module carry a Class 4 Laser rating it emits invisible laser radiation（1064 central emission
wavelength）with a rated average output power of over 10W and rated peak power of over 7kW.

1. Product Tour
1.1 Product Description
The JPT YDFLP pulsed fiber laser adopts the MOPA (Master Oscillator Power Amplifier)
configuration, in which a semiconductor laser diode serves as the master oscillator and the fiber
amplifiers boost the output power. For this MOPA pulsed fiber laser, the pulse width and pulse
repetition frequency are able to be adjusted independently. By changing the pulse width of the
fiber laser, the peak power of this MOPA fiber laser can be maintained at the same level for
different pulse repetition frequency. This feature makes the product an ideal laser source for
various industrial applications.
The MOPA fiber lasers get pumps through fiber couplers, which embed them with higher
slope efficiency compared to conventional solid state lasers. The fiber laser is more compact and
easy to carry, because it only uses three cooling fans to effectively remove the heat generated
inside the chamber. Besides, the all fiber based laser cavity enables higher beam quality of the
laser output.
JPT’s MOPA fiber laser adopts the standard DB25 interface, and it is power supplied with
24V/8A DC power supply, which makes it a good compatibility. A photograph of a typical JPT
MOPA fiber laser is as shown in Figure 2.

1.3 Operation conditions and safety instructions
In order to maintain good performance and reliability of this product, please always operate the
laser under normal conditions as below:
1) This fiber laser shall be operated with 24V/8A DC power supply; wrong connection will
lead the fiber laser can’t work
2) There should be 10-cm-wide air gaps in front and behind the fiber laser chamber, and the air
flow direction should be the same with the fiber laser module and the rest of the whole system;
Short Ventilation distance and wrong air flow direction will lead the fiber laser can’t
work.
3) The operating temperature should be 0~40℃; the fiber laser will alarm internal if the
temperature above 40℃; it’s a protection action in order to insure the long time operational
reliability.
4) Please keep the laser module clean during the operation, especially for the fiber pigtail and
output isolator; please remember cover up isolator exit during nonworking time.
5) Power off the product before installing or uninstalling this fiber laser;
6) Never look at the fiber laser head, and please wear laser goggle when operate this fiber
laser;
7) The YDFLP-X-RE/LP(1/2)+-X-X pulse width is fixed at 200ns. If you need other fixed pulse
width, please contact us for customization;

The cut-off frequency is the minimum frequency that the laser can be operated with maximum
peak power and average power. Please operate the fiber laser at frequency higher than the cut-off
frequency.
*Above the cut-off Frequency value is the fiber laser full power output range, oppositely,
below the cut-off frequency value is the cut-off power output range. That means the fiber
laser will reduce the output power to protect the machine when below the cut-off frequency
value. Below is the charts that showed the change between frequency and output ：
Figure 3 Cut-off Frequency & Output power relationship charts
* Remarks:
Threshold frequency = Cut-off frequency, of which the definition are the same.

A--System Initialization: The laser can accept signal only after 12s switch on the laser
power.
B--Pump charging time: Range (8ms-35ms), 8ms is recommended.
C--Range: 1ms-8ms, 4ms is recommended.
D--Frequency switching time: Range: 4-8ms, 8ms is recommended.
E--Class II SIMMER This value is for controlling the height(power) of the first pulse
which can be adjusted via GUI (the supporting software of the laser).
F--The height of the first pulse: This can be adjusted via GUI (the supporting software of
the laser).
Remarks: After provide 24V voltage, you need to wait 12s before use the laser.
①Fiber laser control system self-locking: If fiber laser received unusual warning signal
(Such as: higher temperature, the 24V power supply is too low) the fiber laser will stop to
work. Please restart the fiber laser if you need to recover the machine.

4. Operation Procedure
4.1 Preparatory examination of the product
1）Check the laser casing and the fiber cable for any unexpected conditions;
2）Check the connection between laser system and the fiber laser module, and tighten the
connection cable.
4.2 Operation Procedure
1）Power on the system
Turn on the fiber laser at the same time or after turning on the marking machine. Wait for about
12s before using the laser.
2）Procedures for laser marking
To test the fiber laser, firstly please set the power to 0% and draw a simple figure using the laser
marking software, drive the marking and observe the laser output using the laser test plate. Then
gradually increase the laser power and change the settings for the marking process. Under
normal circumstances, the laser output should be stronger and stronger on laser test plate; If not,
turn off the machine and check it.
4.3 Precautions during the laser operation
1）Wear laser safety glass.
2）Please stop the laser processing before turning off the fiber laser.

5.2.2 Use GUI to Control Laser
1) Control Mode Option
When we select all parameters controlled by GUI. The setting will be saved and has data
power-off memory function. Therefore, we should cancel the GUI_Control mode each time
when we don’t want to use GUI to control the laser.
Laser is able to work at the parameter set by GUI like power, frequency and pulse width.
Laser On: set the parameters you want and click “laser on”,the “on” light become green means
laser start. “off” light become green means laser off.
Language: In the English interface, click "中文" will switch to English, in the Chinese interface,
click "English" will switch to English.
2) Default Set of Laser
Laser can set the default parameters through this Default_SET,like SIMMER,Pulse
Width,Repetition Rate and others,any change will work immediately and it support data
Power-Off memory function.

Def_SIMMER：To control the amplitude of the first pulse. The larger the value is, the higher the
first pulse will be.
[Suitable SIMMER] [Too High SIMMER] [Too Low SIMMER]
Def_PRR: Under internal PRR mode, the system will output based on the default PRR if no
external frequency signal is detected.
Def_pulse: The system will output laser pulses with default pulse-width if it cannot be
controlled externally.
EXT.PRR: Tick this choice to use the external frequency mode (The final output laser pulses
will be synchronized with external frequency signal. This mode can be used when the control
card has optimized the external signal). If un-ticked, internal frequency mode will be selected
(System will firstly calculate the external frequency signaland then generate the pulse signal
internally. This mode can be used to define the default PRR of the laser when there is no external
frequency signal detected by the control card.
The default mode is external frequency mode.
