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.

915nm 3W IR MM Fiber Coupled Laser System

Usually we often see visible lasers, but few people will test infrared invisible lasers. Today we tested a 915nm infrared laser and its output power of 3000mW. Then when it is coupled through the fiber, what is the output power of the fiber end? Let’s check it now.

The optical fiber can be customized. 100μm~1000μm fiber is optional, the coupling efficiency of different fibers will be somewhat different. The larger the core diameter, the higher the coupling efficiency, usually the coupling efficiency is 80%~90 percent. In addition, the fiber length and interface also can be customzied. Here is 1000μm, SMA interface fiber.

The output power of the laser is adjustable from 0 to 3000mW, which can be adjusted by the knob. It supports 3 working modes, CW/TTL/Analog, switch the working mode on the back of the laser power supply. In TTL/Analog modulation mode, an external modulation signal needs to be connected.

660nm Red Semiconductor Laser Coupled Fiber Optic

What I’m going to talk about today is 660nm 1800mW fiber laser system. It supports 3 working modes, CW/TTL/Analog. In TTL/Analog modulation mode, an external modulation signal needs to be connected. In addition, the Lock crystal head cannot be pulled out. External signal Mod Input, no need to connect in CW working mode.

The optic fiber can be customized. Here is 1000μm SMA905 interface fiber. 100μm to 1000μm fiber is optional, the coupling efficiency of different fibers will be somewhat different. The larger the core diameter, the higher the coupling efficiency, usually the coupling efficiency is 80~90%.

To adjust the output power by adjusting the working current:
Turn the ‘Adjustor’ knob clockwise, when the current exceeds the minimum working current, the Laser indicator light turns green, and there is laser output at this time. When the ‘Adjustor’ is rotated clockwise to the end, it is the max working current and the max output power of the laser. In addition, the red STOP button is used for emergency stop, and it is not used under normal circumstances.

This is a 1615nm 200mW infrared fiber coupled laser source. The output power is 0~200mW adjustable by adjusting the working current. Turn the ‘Adjustor’ knob on the power supply clockwise, when the current exceeds the minimum working current, the Laser indicator light turns green, and there is laser output at this time. When the ‘Adjustor’ is rotated clockwise to the end, it is the max working current and the max output power of the laser.

Today we are talking about software-controlled laser system. This is 450nm blue fiber coupled laser source controlled by software. EasyHost is the control software. The connection between the laser and PC software adopts the communication protocol of RS232. The laser supports two working modes: CW/Modulation. When switching to Modulation, an external signal input is required. This is a fiber-coupled laser, and a free-space output laser can also be customized.

Software operation:
Click the [Open COM] button to connect the control circuit of the laser. Multiple laser working parameters can be viewed/set in the software. As a special reminder, it is necessary to set amaximum working current parameter according to the current laser, so as to avoid the later adjusted current being too high and damaging the laser.
