1.3. Environmental requirements and cautions
Pulsed laser should be driven by 24VDC±1V 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 contamination. 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 operation of the device.
h) Make sure the pulse repetition rate(PRR) is higher than 1kHz.
i) The longest time without pulse is only 100
s
. If there is no pulse output, please stop marking
at once to avoid the further damage of the device.
j) 10) Power source sudden interruption will do great harm to the laser device. Please make sure
the power supply works continuously.
1.4. Specifications
Technical Data are shown in Table 1. The possible pulse repetition rates (PRR) and the maximum
average energy P for different duration τ are given in the Table 3.
Note that a pulse duration of τ =600 ns in theTable 3. is continuous mode,and continuous laser is
output for any frequency setting. The waveforms for different pulse duration τ for their maximum pulse
at the cut-off repetition rate PRR
0
are shown in Figure 4. When any pulses of a pulse
duration from τ =2 ns to τ =500 ns (see Table 2.) are used, the nominal output rated power is P
max
=20W,
if the pulse repetition rate PRR is greater than the corresponding cut-off pulse repetition rate PRR
0
. If
the pulse repetition rate PRR is less than the cut-off frequency PRR
0
, the output power is linearly
related to the pulse repetition rate, as shown in the Figure 3. below.

form, and delivers the most significant bit as the priority.
2) The order structure from marking machine to the laser machine is:
0xA5+instruction code.
3) 0xA5(A5h)is the comment byte to active the laser pulse duration control port.
0xA5 and the following data will be directly sent as the serial input form to the
Pin2 on the DB25 port.
4) The input data length is 4 bytes: the first byte of instruction code should be 0x01
(01h),the second byte and the third byte are the value of the binary coding of
laser duration (for example: 200 is the decimal number of 0x00C8, represents the
setting pulse duration is 200ns).
5) Pin22 is the Enable signal. The Enable should achieve high state at least 10us
before Pin2 and Pin3 changing. The Enable should achieve low state at least 10us
after Pin2 and Pin3 changing. Figure 3.4 shows the adjustment process of laser
duration control.
6) Pin19 should decrease to low state before adjusting laser pulse duration.

For example, if using Beijing JCZ Technology Co. marking card to adjust laser pulse
duration, the setting processes are described as follows:
a) Make sure the power supply, DB25 cable, control card and computer are correctly
connected, and then turn on the 24V power supply.
b) Open Ezcad2.7.6 (or other versions), then click ‘F3’, the configuration parameter
should show up, select ‘Fiber’ in the category of the ‘Laser Control’ panel, follow that
select ‘IPG_YLPM’, and then close this window.
c) Pulse duration can be modified by the ‘Duration’ on the right side of the window. If the
setting duration is smaller than the limiting minimum value, the duration of output laser
will be 2ns (minimum). If the setting duration is larger than the limiting maximum
value, the duration of output laser will be continuous work (maximum). If the setting
duration within the range, the duration of output laser will tend to the smaller side.

1.3. Environmental requirements and cautions
Pulsed laser should be driven by 24VDC±1V 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 contamination. 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 operation of the device.
h) Make sure the pulse repetition rate(PRR) is higher than 1kHz.
i) The longest time without pulse is only 100
s
. If there is no pulse output, please stop marking
at once to avoid the further damage of the device.
j) 10) Power source sudden interruption will do great harm to the laser device. Please make sure
the power supply works continuously.
1.4. Specifications
Technical Data are shown in Table 1. The possible pulse repetition rates (PRR) and the maximum
average energy P for different duration τ are given in the Table 3.
Note that a pulse duration of τ =600 ns in theTable 3. is continuous mode,and continuous laser is
output for any frequency setting. The waveforms for different pulse duration τ for their maximum pulse
at the cut-off repetition rate PRR
0
are shown in Figure 4. When any pulses of a pulse
duration from τ =2 ns to τ =500 ns (see Table 2.) are used, the nominal output rated power is P
max
=20W,
if the pulse repetition rate PRR is greater than the corresponding cut-off pulse repetition rate PRR
0
. If
the pulse repetition rate PRR is less than the cut-off frequency PRR
0
, the output power is linearly
related to the pulse repetition rate, as shown in the Figure 3. below.

1) Marking machine
sends
the command to the laser machine by the Pin2 on the DB25
port, meanwhile sends the clock signal to the Pin3. The comment is the binary
form, and delivers the most significant bit as the priority.
2) The order structure from marking machine to the laser machine is:
0xA5+instruction code.
3) 0xA5(A5h)is the comment byte to active the laser pulse duration control port.
0xA5 and the following data will be directly sent as the serial input form to the
Pin2 on the DB25 port.
4) The input data length is 4 bytes: the first byte of instruction code should be 0x01
(01h),the second byte and the third byte are the value of the binary coding of
laser duration (for example: 200 is the decimal number of 0x00C8, represents the
setting pulse duration is 200ns).
5) Pin22 is the Enable signal. The Enable should achieve high state at least 10us
before Pin2 and Pin3 changing. The Enable should achieve low state at least 10us
after Pin2 and Pin3 changing. Figure 3.4 shows the adjustment process of laser
duration control.
6) Pin19 should decrease to low state before adjusting laser pulse duration.

For example, if using Beijing JCZ Technology Co. marking card to adjust laser pulse
duration, the setting processes are described as follows:
a) Make sure the power supply, DB25 cable, control card and computer are correctly
connected, and then turn on the 24V power supply.
b) Open Ezcad2.7.6 (or other versions), then click ‘F3’, the configuration parameter
should show up, select ‘Fiber’ in the category of the ‘Laser Control’ panel, follow that
select ‘IPG_YLPM’, and then close this window.
c) Pulse duration can be modified by the ‘Duration’ on the right side of the window. If the
setting duration is smaller than the limiting minimum value, the duration of output laser
will be 2ns (minimum). If the setting duration is larger than the limiting maximum
value, the duration of output laser will be continuous work (maximum). If the setting
duration within the range, the duration of output laser will tend to the smaller side.
