Safety Information
Please read this manual carefully before operating the YDFLP fiber lasers.
In order to ensure the safe operation and optimal performance of the product, please
strictly follow the safety notification below.
●Make sure that the 48V DC power supply is connected in the correct way. Inappropriate
connection might damage the laser.
●To prevent electrical shock, please do not remove the laser cover. Warranty will be
invalid if warranty label is removed.
●Please wear appropriate laser safety goggle (see below Fig.1.) before emitting the laser.
We recommend OD4+ goggle or better. This laser module carries a Class 4 laser rating,
which emits invisible 1064nm wavelength laser radiation with average output power
over 60W and peak power over 10kW. Both direct beam and reflected beam will cause
permanent damage to the eyes, skin, and might cause fire.
●Caution: Even at 0% power emitting, the average output laser power is still around
100mW.

1. Product Introduction
1.1 Product Description
JPT E-M7 Series fiber laser control with standard DB25 interface and powered with 48V DC.
It is designed for high-speed and precise marking application. The pulse response and
performance are much better comparing to similar products. Significantly compact size is ideal
for small marking system.
Photographs of typical E-M7 type fiber lasers are shown in Fig.2 and Fig.3 ( For the specific
appearance, please refer to the appearance of the product shipped):

1.3 Operation Conditions and Safety Instructions
Please read the following instructions carefully. Product reliability and lifetime probably be
affected if not following the user manual.
1. Make sure that the 48VDC power supply is connected in the correct way. Wrong
connection or input voltage might damage the product.
2. Make sure that the bending diameter of the fiber cable is larger than 15cm in
anytime. Otherwise power will decrease or the laser may even be damaged.
3. The speed of the fan is adjustable according to ambient temperature. Make sure that
minimum10cm air gaps behind and in front of the fiber laser. And the air flow direction of the
system should be the same as the laser. Short ventilation distance and wrong air flow
direction will lead to the laser temperature rises.
4. The default running ambient temperature range is 0~40℃. Enable the “Performance
Mode” by GUI, the average output power can be increased by 20% under this mode when
at the same cut-off frequency. The operational temperature range 5-35℃ is recommended
at this point. The sensor might be alarm if temperature beyond 5-35℃ and continuous
emitting the laser under the high energy. (Please refer to the introduction of monitoring
function and alarms in Chapter 3.2.) It is recommended that the operating temperature range
of the laser is 10-30℃. Good heat dissipation is helpful to prolong the working life of the laser.
5. Due to the "thermal lens effect" of ordinary K9 glass optical lens in medium and high
power range application, the phenomenon of focus drift, spot size inconsistency or light output
instability might occur during material processing if using K9 glass optical field lens. Fused
silica lens is recommended.
6. Please keep the fiber laser source clean especially the laser output window. Please
remember to cover the output window when it’s exposed to the open environment. Dust on the

YDFLP-E-80&100-M7-M-R User Manual
3File Number: JG-MCYF-SM-0039
window will cause heat and damage the lens, which results in output power decrease even
laser damage.
7. Please make sure that the power is off before installing and uninstalling.
8. Please do not look at the output window anytime when power on, and wear laser safety
goggle when operating the fiber laser.
9. YDFLP-E-80&100-M7-M-R contains 17 wave-forms: CW, 2ns, 4ns, 6ns, 9ns, 13ns, 20ns,
30ns, 45ns, 60ns, 80ns, 100ns, 150ns, 200ns, 250ns, 350ns, 500ns.
Other pulse width is available for customization request.

2. Laser Interface
2.1 Power Supply Connector
Please refer to Figure7 & Table 6 in below to install the power cable to the 48V DC power
supply, and ensure the DC power supply can provide sufficient output power. Please also note
the polarity of the cable when connecting. The “main+” and “control+” at the end of the power
cable are 48V DC positive, “main-” and “control-” are 48V DC negative, “Earth” is the ground
wire.
Figure 7 Diagram of the power supply cable
"Main +" and "Main -" are power supply pins of laser pump, "Control +" and "Control -"
are power supply pins of control circuit. If independent power supply function is not required,
main and control power cable can be used in parallel.
The power interface of the laser is DB-7W2 plug (male), and the pin distribution is as follows:

Note 2: The default setting is red beam preferred. Red beam Pin22 signal has higher priority than
MO and PA signal. When Pin22 signal is high, MO and PA signal will be shut down internally.
The laser can be emitted by restarting MO and PA after Pin22 signal is low. Priority mode can be
set up in GUI (please refer to Chapter 3.1.2).

10us in advance before adjusting the serial input and the serial clock signal.
T2: the duration is 10us. After pulse width adjustment, it needs to delay 10us before closing.
If the user sets 350ns pulse width, the input instruction is: 0xa5 → 0x01 → 0x01 → 0x5e,
where 0x01 and 0x5e represent the pulse width value 350.
The parameter of this instruction is the binary value of pulse width.
The user can compile any pulse width, but the laser only accepts the specified pulse width
(refer to the specifications of various versions for specific pulse width). If the given pulse
width is out of the range, the laser will output with the close pulse width value.
3. JPT GUI Laser Testing Software-TypeE
TypeE is designed for YDFLP-E series laser. It has multiple functions including laser
control, setting the default parameters, setting the control mode, alarm monitoring, DB25
interface monitoring, internal parameters monitoring etc. Using the matched GUI software for
