Thank you for the link Wil be starting to design some circuits to use on low power diodes to 1W diodes but higher power diodes wil be a project after getting used to linear power supplies

I am learning myself elctronics that i am finished with school and starting with low power and easy to control like transistors and they are not perfect but it is my good start until i know how to work with switching supplies My biggest problem as n beginner is choosing the parts for a circuit...

What is your most complicated laser circuit design for the case in high power lasers I want to go and build a circuit for my future lasers that is not the LM317 regulator or anything but a circuit that uses opamps and transistors for current regulation.

I am building some lasers with a 505nm diode and 405nm but need info what a laser diode need to work at its rated power When I power the 405nm laser diode with 5V the voltage output wil drop to 3.5V as it is current limited for the laser, but the question is should I increase the voltage that it...

Where does laser diodes from aliexpress come from I bought a 505nm 30mw SHARP laser diode and cost me 7 USD a wonderd why is it cheap and where does it come from And the 405nm laser diodes cost also alot cheaper but from different online sellers it is 200 USD
