1. Description
1.1 Description
MFP-20 pulsed Ytterbium fiber laser is the one of most advanced products of
MAXPHOTONICS. It is a revolutionary, new, high-performance OEM device which
was developed for integration into high-speed, high resolution laser marking systems.
The main advantage of the MFP-20 offers over ten times improvement in per-Watt
optical power efficiency as well as low power consumption and practical robust design
over traditional diode-pumped solid-state lasers, and is suitable for either laboratory or
field operation. The source has a compact, rugged, stand-alone, ready-to-use, turn-
key design and can be directly integrated into user’s apparatus.
The laser emits periodical pulse train at 1064 nm wavelength and peak power up to 20
KW. Pulse repetition rate can be controlled either via separate remote control unit or
by external PC. The laser requires an 24V external DC power supply.

WARNING: This device has output optical head connected to the MFP-20 by
fiber cable. So please, be careful dealing with output head. Do not
separate the fiber and the laser head.
WARNING: If this instrument is used in a manner not specified in this
document, the protection provided by the instrument may be
impaired. This product must be used only in normal conditions.
WARNING: Do not install collimator when laser is active.

MAXPHOTONICS CO.,LTD
WWW.MAXPHOTONICS.COM 7
WARNING: MFP-20 Fiber Laser Module has three fans at the rear panel for
active cooling. Make sure that there is sufficient airflow to cool the
device.
WARNING: NEVER look directly into output head and make sure that you
wear appropriate laser safety glasses at all times while operating
the product.
WARNING: When you marking on the copper material, please do not to make
the marking area in the central ,or it will be damaged the laser.
WARNING: Power supply interruption is very dangerous for the equipment,
please provide continuous uninterrupted power supply voltage
CAUTION: In addition to the manual of controls or adjustments or
performance, other operations may cause the risk of radiation
exposure
CAUTION: It’s essential to keep the output lens cleaning. After use, please re-
covered the collimator.. Do not touch the output lens,. Please use
the lens tissue to clean it and do not use any solvents to clean.
CAUTION: Please follow the above guides to process, if not, it will cause
damage to the optics components, which should be excluded in
the warranty range.

4. Pin16 and Pin21 are for warning, the 2 Pin show the situation as followings.
5. Pin18 is the switch sign of MO（main surge）.MO should be turn on before 4ms when
open the Booster（BS）.After turning on the MO ,the laser will have some electricity
consumption.
Notes：MO and Pin18 should be turning on at the same time.
6. Pin19 is the input end of launching controller Booster（BS）.when level is H, please
turn on the BS，when level is L, please turn off BS, when the Pin19 change to lever

MAXPHOTONICS CO.,LTD
WWW.MAXPHOTONICS.COM 13
H, the laser will be out after stated delay. When the level is L, the laser will be turned
off after stated delay.
Notes：
a. MO should be turned on before 4ms of BS, if not, it will be no laser output.
b. If turning on the BS first, then the MO，the laser will be out after 1~4ms. The
above two situation is not list in the manual as they are unusual operation, please try
to avoid them. BS should be turned on together with the data rising.
7. Pin20 is the input interface of in-phase，The pulse of laser output should be the same
steps with signal rising at the stated range ,the pulse repetition rate from this side to input
（PRR）（referring the limitation of PRR）.
Notes：if the input PRR above the stated range, the protection system of laser will
protect the loop and recruit the loss pulse or limitation the data of PRR.
8. Pin23 is the input interface of “emergency stop”. When running ok, the level should
be H, once the level change to L, the laser will be stopped automatically（the same with
MO&BS）which isn’t depend on the other control signal. When restart the laser, please
make sure that the level of MO &BS should be down to L （if the original is H）.If need
the laser running normally, this signal should be at H level 2μs earlier before offering the
MO&BS.
Laser Running
1.Please take off the protecting covering from the laser output head.
2.Please connected the laser mold and control system through DB-25 interface, please
make reference from the leading of DB25 if necessary
3.Please make sure that the following interface at the initialization rightly
a) Pin18，19，22，23 at level L ；
b) The Repetition frequency of Pin20 at the stated range
4. Connected the 24VDC power and laser power line（+24V to brown，ground to
green/yellow，- to blue）
5. Laser will be running after 120s when gaining the 24VDC power（warming-up time）.
Notes：it’s allowing to offer the 24VDC main power first，then make the control
signal initial
6. Make the emergency stop to（Pin23）H。
7. Set up the required power through Pin1~8.

MAXPHOTONICS CO.,LTD

8. Set up the Pin18 to and turning on MO.
9. Waiting about 4ms.
10. Through Pin19 to modulate the laser. Input H/L to control the laser’s switch. The
up and down time have been limited（referring the specification）The modulate
speed can not be faster than the total value of up and down’s time. The typical time
should be 250us，the period of modulate should be above 500us（the related
frequency should be 2kHz）.
11. After finished a turning on/off operation, and wait for the next task, if the time above
20ms,please turn off the MO，and it can decrease the power consumption, extend the
using life of MO, and avoid the balance power output of MO.
12. When finished a task, please turn off the BS &MO（Pin18 & Pin19 should be L ）.
13. Cut down the power of 24VDC .

finished
1.1.2 Checking the signal of marking system and fiber laser power.
MAXPHOTONICS CO.,LTD certifies that this instrument has been thoroughly tested
and inspected, and found to meet published specifications prior to shipping.
NOTE: Upon Receiving your device check the packaging and parts for any possible
damage that may have occurred in transit. If damage is apparent please contact
MAXPHOTONICS CO.,LTD immediately.
4.2 Operation Steps
4.2.1 Operation Steps
Turn on the fiber laser power, then the marking system power(make sure that the fiber
laser power on and the fan running within the 180s warm-up time of the marking
system ),otherwise, should return-on according the order and turn on the computer
power at the end.
4.2.2 Operation steps of checking laser marking system after turning on
When start to test the fiber laser after start-up finished, please set up the power to
0W,then make a picture, marking continually and add the power from 0W to 20W.
And also to test by using a camera paper, and notice that the laser must be getting
stronger( the step should be taken when starting the machine each time, please turn
off the machine to check when the laser does not become stronger or there isn’t any
laser. After the work in order, marking can be started following the normal procedure.
4.3 Warning
4.3.1 The highest frequency should be70KHz
4.3.2 Please be careful when you adjust the rate of frequency when marking, or it will
influence the marking results.
4.3.3 It’s workable for MAXPHOTONICS fiber laser to turn off the laser power directly
