Useful software for lasers and laser engraving cutting machines.
Diy laser driver.
The potentiometer 10k and resistor are used as the voltage limiting circuit connected with the adjustable pin1.
1 produce constant regulated voltage.
Here is a great video on how to make a laser diode driver.
2 produce constant current driven through the ld load.

They can work in two ways.
Follow this simple video and you shall not be disappointed.

The second type is more easy to design and us.
This capacitor is used to filtering high frequency noise from our dc source and gives to input pin3 of the lm317 voltage regulator ic.
Constant current is just what it states a constant output level over time say 30 ma in theory forever if needed.

As battery start giving supply it first flow through the ceramic capacitor 0 1uf.
At a very general level there are a few classes or types of laser drivers which you will hear commonly discussed.
