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 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 ideal laser source for
various industrial applications.
The MOPA fiber lasers get pumps through fiber couplers, which enables 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 whole fiber based laser cavity enables higher beam quality of
the laser output.
JPT MOPA fiber laser adopts the standard DB25 interface, and it’s power supplied with
24V/5A DC, which makes it a good compatibility. A photograph of a typical JPT MOPA fiber
laser is as shown below.

1.3 Operation conditions and safety instructions
In order to maintain good performance and reliability of this product, please operate the laser
under conditions as below:
(1) This fiber laser shall be operated with 24V/5A DC power supply; wrong connection will
damage the fiber laser, which lead to the 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 direction of the fiber laser system; Short
ventilation distance and wrong air flow direction will lead to 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 fiber laser source clean during the operation, especially for the fiber
pigtail and output isolator; please remember cover the isolator when the laser is unworking.
Dust on the isolator will cause heating and lens damage, which results in the laser
output power attenuation
(5) Please ensure the power is off before install and uninstall this fiber laser.
(6) Never look at the fiber laser head, and please wear laser goggle when operate this
fiber laser;
(7) The YDFLP-C-M7 contains 16 waveform: 1ns, continuous,
2ns,4ns,6ns,8ns,13ns,20ns,30ns，45ns,60ns,80ns,100ns,150ns,200ns,250ns,350ns.

★for laser safety and long lifetime, when set ≥80ns, ≥400kHz, frequency will be limited at 400kHz,
*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 fiber laser when below the cut-off frequency value.
Below is the chart that shows the change between frequency and output:
