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 the +24VDC 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 void
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
20W and peak power over 7kW. Both direct beam and reflect 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 type fiber laser control with standard DB25 interface and powered with 24V/5A(10A)
DC. It is designed for high speed and precise marking applications. The pulse response and
performance are much better comparing to the similar products. Significantly compact size is
perfect for smaller marking system.
Photographs of typical E type fiber lasers are shown in Fig.2 and Fig.3 ( the specific
appearance is subject to actual delivery):

1.3 Operation conditions and safety instructions
Please read the following instructions carefully. Product reliability and lifetime probably be
effected if not following the user’s manual.
1) Make sure the +24VDC power supply is connected in the correct way. Wrong connection or
input voltage might damage the product.
2) Make sure the bending diameter of the fiber cable is larger than 15cm in anytime. Otherwise
will cause power lost even laser damage.
3) Make sure 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 rise.
4) The laser running ambient temperature range is 0~40℃, laser will get internal alarm if out of
this range. It’s a protection action to insure the lifetime of the laser.
5) 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 lost even laser damage.
6) Please make sure the power is off before installing and uninstalling the fiber laser.
7) Please do not look at the output window anytime when power on, and wear laser safety goggle
when operating the fiber laser.
8) The standard pulse width is 200ns for YDFLP-E-20&30-LP-S and YDFLP-E-50-LP-L. Other
pulse width is available for customization request.

★ The maximum output frequency will be limited to 600kHz.
*The laser will have expected output power when working above power reduction frequency.
When working below power reduction frequency, the power will drop accordingly to maintain the
output peak power. Below chart shows the relationship between frequency and output power:
