What our laboratory demonstrates today is a 940nm fiber coupled laser module that can be controlled by software. It means that we can control the output power on the computer. The max power of this laser is 30W, and you must wear infrared laser protective glasses when operating it.
First, let’s introduce each indicator light on the laser module and what it means:
After plugging in the 12V power supply, the PWR (Power) indicator light lights up. ACT(Active) is the Laser ON/OFF switch. When in the ON state, the indicator light lights up. When in the Active ON state, the LASER indicator light will also light up, indicating that there is laser output.
Turn on the laser, set the operating current through the software, and display the current laser output power.
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.
