Laser diodes do not require a driver circuit
If you buy a single laser diode as a standalone component, you need to set up a driver circuit that controls the current through the laser diode. Not an option Any driver circuit for diode lasers should include a well-filtered power supply that, as efficiently as possible, blocks inductive loads and other. While laser drivers are essential for most applications, there are some specialized cases where they might not be necessary: Simple LED-Based Lasers: Some low-power laser diodes, often used in simple applications like pointers or indicators, may not require a dedicated driver. It has three pins; two for connecting 5V and GND, and one for turning the laser on and off.
