Hi,
I found this page speaking about a Light Controller but i didn't understand the utility of such a board. what i understood is that it allows to control the pulse duration of PWM (pulse width modulation).So my question is :Can this board be a power controller of a laser source?

thank you in advance.

Can your laser be controlled by PWM?, all the circuit is doing is providing a pulsed supply voltage - and at a very low frequency, only 610Hz.

SFB, I thought the purpose of the board was crystal clear, what are you having difficulty understanding?

Why drive a laser diode directly, laser modules with built in drivers are cheap and common, typically they only need a current limiting diode to limit absolute current, the feedback circuit on the module handles the stability while running.

What if he want to power a 80 watt laser ? 100VDC 15 Amp?

csaba we can guess and what if till the cows come home and get absolutely no where if SFB doesn't clearly state what he's trying to do or what the confusion was.
