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 with a rated average output
power of over 10W and rated peak power of over 7kW. Contact with direct or scattered laser
radiation will cause permanent damage to the eyes, burn human tissue and start fires.

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 idea 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 unworking 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-M6+ contains 16 pulse width to choose: 1ns,2ns,4ns,6ns,9ns,13ns,20ns,30ns，
45ns,55ns,60ns,80ns,100ns,150ns,200ns,250ns.If you need other pulse width, please contact

For safety concern, when pulse width ≥80ns , frequency ≥400 kHz, input and output
frequency is as shown in the figure below:
*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 ：

the clock signal through Pin3. Instruction description will be transmit in binary system, and
first transmit the most significant bit.
2）Fiber laser instruction structure as below：
3）OxA5(A5h) is the data transmission activated byte of activated pulse width control interface,
OxA5 and all data byte is transmit to Pin2 serial input.
The data length is 4 bytes.
The first byte of instruction code is 0x01.
The fiber laser will be at high level status at least 10us in advance before changing “Enable”
at any connector, and will be at low level status at least 10us after all change finished.
All instruction design start with 0xA5 byte

The parameters of this instruction are the binary values of the pulse width. Users can compile
any values of pulse width, but the laser can only receive the signals of specified pulse width
(please refer to the user manual for specific pulse width). If the value of pulse width is out of the
range of specified pulse width, the laser will choose the default pulse width set last time.

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
1 minute before move on to the next step. Please take note that the fiber laser will be locked
automatically if the laser control card has not been power on within 5s after turning on the laser.
If so, please restart the fiber laser in order to function normally.
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 frequency doubling
piece of pottery and porcelain. Then gradually increase the laser power and change the settings
for the marking process. Under normal circumstances, the laser output observed using the
frequency doubling piece of pottery and porcelain should be stronger and stronger, or else, turn
down the machine and check it.
4.3 Precautions during the laser operation
1）Wear laser safety goggle;
2）Please stop the laser processing before turning off the fiber laser.
