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 24V DC power supply is connected in the correct way. Inappropriate
connection might damage the product.
●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 M7 Series fiber laser control with standard DB25 interface and powered with 24V 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 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.
1.3.1. Make sure that the 24VDC power supply is connected in the correct way. Wrong
connection or input voltage might damage the product.
1.3.2. 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.
1.3.3. 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.
1.3.4. The required running ambient temperature range is 0~40℃. Laser will get internal
alarm if out of this range. 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.
1.3.5. 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.
1.3.6. 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
window will cause heat and damage the lens, which results in output power decrease even laser
damage.
1.3.7. Please make sure that the power is off before installing and uninstalling.

1.3.8. Please do not look at the output window anytime when power on, and wear laser
safety goggle when operating the fiber laser.
1.3.9. YDFLP-E-60-M7-L1-R contains 17 wave-forms: CW, 2ns, 4ns, 6ns, 9ns, 13ns, 20ns,

Data length of input laser is 4-bit bytes.
The first byte of instruction code is 0x01.
The Pin22 signal needs to be turned on 10us in advance before sending Pin2 and
Pin3 signals. After finished pulse width adjustment, Pin2 and Pin3 signals need ≥10us
delay before turning off Pin22 signal (as shown in Figure 14).
All instruction design starts with byte 0xA5.

Pulse width time sequence
The following figure is an example to illustrate the sampling series diagram with a
pulse width of 200ns. The series of 0x01 bytes of instructions is as follows:
Example: 0xa5 → 0x01 → 0x00 → 0xc8
0xa5: for activating pulse width control instruction
0x01: for setting pulse width instruction
0x00 and 0xc8: set the pulse width to 200ns.

T1: the duration is 10us, and the enabling signal of pulse width adjustment needs to be turned on
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.
