How to use a Laser Diode?

If we want to operate a Laser diode then we must have laser diode driver circuit. As it helps in limiting current then supply it to laser diode. A laser diode can only work properly with the help of this circuit, if we directly connect it to the supply, because of having more current it will damage and if the value of current is low then the laser diode will not operate. Laser Diode driver circuit helps in providing a correct value of current to operate the laser diode. For making a laser diode driver circuit we need a few no. of components like resistor, capacitor and a voltage regulator IC.

The first capacitor in the circuit filter the High-frequency noise from the DC supply. The second capacitor works as power load balancer used to filter the fluctuating signals of output voltage. And a voltage regulator IC is used to provide a fix output voltage and we can adjust the output voltage by changing the value of resistor. You can use a potentiometer instead of resistor (R2) to adjust the intensity of laser light.
