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 do according to following warnings, cautions and

other information.

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 24VDC power source is

connected and the anode and cathode are right. Failure to connect power source correctly will

cause damage to the device.

The device emits invisible 1060~1085nm wavelength light with average power 10W～50W.

Do not expose your eyes or skin to the radiation of the laser.

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.

Do not look into the light output end directly. Use appropriate laser safety eyewear when

operating the device.

Safety labels and locations

The two labels above is located on the top of the cover of the device, representing laser

radicalization.

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 1060~1085nm wavelength pulsed light under the control of industrial

laser’s standard interface driven by 24VDC power source.

1.3. Environmental requirements and cautions

Pulsed laser should be driven by 24VDC±1V power source.

1) Caution: Make sure the corresponding wires of the device are properly grounded.

2) 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.

3) 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.

4) If the operating the device fails to follow this instruction, the protective function will be

weakened. Therefore, it should be used under normal conditions.

5) Do not install the collimating device into the output head when the laser device is in working.

6) 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.

7) 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.

8) Make sure the pulse repetition rate higher than 20 kHz.

9) 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.

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

the power supply works continuously.

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

the DB25 are defined as follows in Fig. 5.

1) 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:
