1. Description
1.1. Product description
Raycus pulsed laser is an ideal high power laser source with high speed and high efficiency.
It is specially designed for industrial laser making system and other applications.
Compared with traditional lasers, pulsed laser has some unique advantages in increasing the
conversion efficiency of the pump light 10 times higher. Its low power consumption and
automotive design make it appropriate for operating both in and outside the lab. Besides, it is
exquisite and convenient for its independence in placement, free time in using and facility in
connecting to equipment directly.
The device can emit 1060~1085 nm wavelength pulsed light under the control of industrial
laser’s standard interface driven by 24 VDC power source.

1.3. Environmental requirements and cautions
Pulsed laser should be driven by 24±1 VDC power source.
a) Caution: Make sure the corresponding wires of the device are properly grounded.
b) All the maintenance to the device should only be done by Raycus, because there is no
replacement or accessory provided with the device. Please do not try to damage the labels or
open the cover in order to prevent against electric shock, or the warranty will be invalid.
c) The output head of the product is connected with an optical cable. Please be careful handling
the output head. Avoid dirt and any other contaminations. Please use the specialized lens
paper when cleaning the lens. Please lid the laser with protective cover of the light isolator to
be against dirt only when the laser is not installed in the device or not in working.
d) If the operating the device fails to follow this instruction, the protective function will be
weakened. Therefore, it should be used under normal conditions.
e) Do not install the collimating device into the output head when the laser device is in working.
f) The device has three cooling fans at the rear panel to dissipate heat. In order to guarantee
enough airflow to help giving heat off, there must be a space of at least 10 cm’s width for
airflow in front and rear side of the device. As the cooling fans are working at blow condition,

if laser is mounted in a cabinet with fans, the direction should be same as laser’s fans.
g) Do not look into the output head of the device directly. Please do wear appropriate laser
safety eyewear during the time when operating the device.
h) Make sure the pulse repetition rate higher than 55 kHz.
i) For the longest time without pulse is only 100 us. If there is no pulse output, please stop
marking at once, to avoid further damage of the device.
j) Power source sudden interruption will do great harm to the laser device. Please make sure
the power supply works continuously.

d) The bending radius of the delivery fiber should not less than 15 cm.
3. Control Interface
There are DB9 and DB25 interfaces at the rear of the laser. The DB9 is a RS232 interface
only used for debugging, no needs to connect. And DB25 is the joint interface connecting control
system with the laser device, please make sure the connection is reliable before operating. Feet
of the DB25 are defined as follows in Fig. 5.

a) The pump current of diode laser and the laser output power are controlled by setting the
value of PIN1-PIN8 (TTL level). PIN1-PIN8 can be set from 0～255，corresponding to the
laser output power from 0～100％(the actual laser power may not be strictly linear with the
setting value). The relationship between PIN value and output power is shown in Table 4:

b) PIN 17 is the external 5 V input, providing power supply for alarm signal: input current >20
mA.
c) Those external input signals (PIN 1-8, 18-20, 22) are connected to the optical coupler inside
the system. Input voltage 3-5 V are defined as digital High, below 1 V are defined as digital
Low. The input current should be above 2 mA.
d) Alarms status: Pins 11, 12, 16 and 21 are the alarm and status outputs which driven by +5 V
power from PIN 17. PIN 12 is reserved (always be high). These pins indicate the following

e) PIN 10、PIN 14 are all digital GND.
f) PIN 20 is the pulse repeating rate signal (PRR, TTL level). If the PRR need to be changed
during the work, it must be changed 5ms earlier than the EM signal turning into high.
g) PIN 22 is the guide laser (red diode) on/off signal. High level switch on the guide laser
while low level switch off the guide laser.
4. Operation Regulations
4.1 Pre-inspection
a) Make sure the device appearance is in good condition and the output fiber is neither
excessively bended nor broken.
b) Make sure signal line of laser and marking system are properly connected.

4.2 Operation procedures
a) Starting procedures
Please make sure the control system is on before you turn on the fiber laser. Only after at
least 1 minute since the power turned on, the subsequent operations can be preceded.
b) Frequency set introductions
For model P60QB, the frequency setting range is from 55 kHz to 100 kHz.
c) Laser marking checking
For the device initial testing, first turn the power down to zero without turning on the
marking system after the device is successfully started. Then draw a quadrate, marking
continuously while slowly increasing the power from zero to 100% at the same time.
Meanwhile, use a ceramic material to observe the laser and the laser should become stronger,
otherwise shut down the device and check. If operating normally, the marking system can be
used in common order afterwards.
4.3 Cautions
a) Marking frequency must be in the range of 55~100 kHz for P60QB.
b) It should not modulate the frequency while marking.
c) Stop marking first before shutting down the device, then turn the power down to zero and cut
the power off.
