Safety Information

Please read this instruction carefully and familiarize yourself with the information we have

provided before you use the product. In this brochure, important operation procedures, safety and

other information are provided for you and all future users. In order to ensure operating safely

and optimal performance of the product, please act according to following warnings, cautions

and other information.

a) Raycus pulsed fiber laser is classified as a high power Class IV laser device. Before

supplying the power to the device, please make sure that the correct voltage of 24V DC

is connected and the anode and cathode are right. Incorrect polarity or voltage will

harm severely the device.



b) The device emits invisible light with a wavelength from





1060nm to





1085nm

with average power of 70W. Do not expose your eyes or skin to the radiation of the

laser.

c) Do not take apart the device, because there are no replaceable accessories available for

users to use. Any maintenance can only be proceeded in Raycus.

d) Do not look into the light output end directly. Use appropriate laser safety eye-wear(i.e.

laser goggles) when operating the device.

Safety labels and locations

1. Description

1.1. Product description

Raycus pulsed lasers are specially developed for high-speed and efficient laser marking

systems. For industrial laser marking machine and other applications provide an ideal high-power

laser energy source.

Compared with traditional laser，pulsed laser can increase the conversion efficiency of

pump light per watt by more than 10 times. Automatic design for high-volume consumption,

suitable for laboratory or outdoor operation, compact, can be placed independent, can be used at

any time, can be directly embedded on the user’s device.

The device can emit 1060~1085nm wavelength pulsed light under the control of industrial

laser’s standard interface driven by 24V DC power source.

1.2. Actual configuration list

Please refer to the included list according to Table 1.

1.3. Environmental requirements and cautions

Pulsed laser should be driven by 24V DC±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.

@2021 Raycus Corporation

f) The device has four 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) The longest time without pulse is only 100



. If there is no pulse output, please stop

marking at once to avoid the further damage of the device.

i) Power source sudden interruption will do great harm to the laser device. Please make

sure the power supply works continuously.

*The output head of the isolator is subject to the final factory product.

2.2. Method of installation

a) Fix the module stable to the bracket and keep the laser in good ventilation.

b) Connect the power line to 24V DC power and ensure enough DC output power. Keep it

clear to the polarity of the electric current: Anode-brown, Cathode-blue, PE-yellow and

green.

c) Make sure that the interface of the external controller matches the laser and the control

cable is well connected to the laser’s interface. The recommended electrical connection

is shown in Figure 4.

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 to the laser system, please make sure the connection is reliable before operation. Feet of

the DB25 are defined as follows in Table 4.

a) The pump current of the 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 to 255，corresponding

to the laser output power from 0 to 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 5.

b) Pin 10 and Pin 14are all digital GND.
