940nm 30W Software Control IR Fiber Laser Module

It is a 940nm IR fiber couled laser module. Its output power is up to 30W and it has two built-in cooling fans. The one shown in our laboratory today can be controlled by software. It means that we can control the output power on the computer.

High-power laser light source is based on high-performance semiconductor laser chip, 105/125μm fiber coupling output. The professionally designed constant current drive and temperature control circuit ensure the safe and stable operation of the laser. Ideal for medical research, fiber laser pumping, and other production testing.

The following are several sets of data we tested today:

Set the working current to 500mA, the laser output power to 194mW, and the laser spot can be seen on the infrared observation card.
The current is set to 2000mA and the laser power is close to 5W. When the laser shines on the sponge, white smoke will emit directly.
The current is set to 6000mA and the laser power exceeds 15W. When the laser shines on the cardboard, it can ignite quickly.

The relationship between operating current and output laser.


Warm reminder: Although this is an infrared laser, it has very high power. You must wear infrared laser protective glasses when operating it.

915nm 60Watt Free Space Output IR Laser System

This time we bring a 915nm high power semiconductor laser. The bottom of the laser module is equipped with a heat sink. Aluminum heat sink and cooling fan can effectively prolong the continuous working time of high-power lasers. There are three working modes of CW/TTL/Analog on the power supply for selection.

The power of 60W is very high power, which can instantly ignite the cardboard. Be sure to pay attention to safety when operating, the operator must wear laser protective glasses, and the laser cannot point to other people or other flammable objects. The rotary button on the power supply can adjust the working current, thereby adjusting the output power.

915nm infrared laser is invisible light, which is invisible to the human eye. Here the laser can easily ignite the cardboard.



520nm 22W Lab Laser Fiber Output PC Control

This is 520nm high power green fiber laser system. This laser adds software control. Use RS232-USB to connect the laser and computer software.The laser output power can be adjusted by software. Using EasyHost software, you can also write your own programs to control the lower computer according to the communication protocol.
The output power is 22W laser, it is a high-power laser, we added a heat sink under the laser module. The heat sink is composed of aluminum sheets and 3 cooling fans. Its fiber is pluggable, here we choose a 1000μm fiber. Let’s check it now.

Software Operation:
Click ‘Open COM’, the software links the lower computer control circuit of the laser. When starting the software for the first time, set the maximum current first, and set a maximum current value according to the laser test report. If the current is too large, it is easy to burn out the laser chip. For each laser, the maximum current must be set first.





1064nm Infrared Laser 10W High Power DPSS Laser

It is 1064nm high power laser with heat sink at the bottom of the laser head. It adopts air cooling mode, with 2 cooling fans. The light outlet has a protective cover. The modulation mode can be selected from the original TTL or Analog, and upgraded to be compatible with both.

When the key is turned ON, the laser starts to work. The knob is to adjust the current size, thereby adjusting the laser output power. Preheat for 1 to 5 minutes, and the laser power reaches the maximum value.


The connector connecting the laser head to the power supply has a protective cover. When installing the laser, it needs to be unscrewed first.




520nm 2800mW Green Diode laser Lab Laser System

This is a 520nm 2800mW green laser system. The laser supports 3 working modes: CW, TTL, Analog. In addition, the Lock crystal head cannot be pulled out. External signal Mod Input, no need to connect in CW working mode. It is free space output by default, fiber-coupled output can be customized.

The laser output power can be adjusted by adjusting the operating current. In addition, the red STOP button is used for emergency stop, and it is not needed under normal circumstances.

880nm 20W Fiber Laser Source NIR Invisiable Laser

This is 880nm 20W high power infrared laser. A fiber coupling interface is added to the laser output port, which can be inserted into a fiber. A cooling device is added at the bottom of the laser module, which is composed of aluminum sheet and cooling fans. The laser supports CW continuous work and modulation work mode, which can be adjusted by the slider button on the back of the laser power supply.

The optical fiber is pluggable, the default fiber interface is FC/PC, and the fiber interface can be customized. The Adjustor button on the power supply is used to adjust the working current, so as to adjust the laser output power. Let’s check it now.

The 880nm laser is a near-infrared laser, basically invisible, only a faint red dot can be seen on the light shield.


High Power Laser 18W 455nm Blue Laser Source

It is 455nm 18W blue laser system. The laser head is equipped with a heat sink. The heat sink has 3 cooling fans, which can effectively extend the continuous working time of the high-power laser. There is a small power interface on the side of the data cable close to the laser head for the cooling fan. In addition, the Lock crystal head cannot be pulled out. External signal Mod Input, no need to connect in CW working mode.

This is a power tunable laser by adjusting the current. Turn the ‘Adjustor’ knob clockwise to adajust the current, when the current exceeds the minimum working current, the Laser indicator turns green, and there is laser output at this time. ‘Adjustor’ rotates clockwise to the end, which is the maximum working current and the maximum output power of the laser. In addition, the red STOP button is used for emergency stop, and it is not needed under normal circumstances.




Safety reminder:
Wear laser safety glasses when operating high-power lasers. It is forbidden to irradiate human eyes and skin with laser light.
