drivers (yet again)

[polop]

hi there.
this is a sircuit designed for an led, from this site http://www.instructables.com/id/Circuits-for-using-High-Power-LED_s/?ALLSTEPS it uses a couple of transistory mosfet things and i was wondering if any of you would know how well it would work in a laser. (hopefully some one can work out what the drop out is)


p.s. just in case THIS IS NOT MY WORK....... (im not clever enough :-[)

I'm not too familiar with it.

But you should have a driver after it.

that circuit is the driver...
however, it would not be very stable, and the current would change with different input voltage
you would need a proper voltage reference to make it work properly
I think...
