I'm looking to drive some laser diodes (50mW) at very modest powers (50%), using simple circuits no doubt less sophisticated than most lab PSUs.
Why does this site say it's not an option? I understand temperature changes, noise, pulses, spikes, inductances and so on, as the page itself describes.
But, since I'll have a lot if headroom, with a rough and ready constant current source that does that it says on the tin I guess, plus more than enough heat dissipation, what's the problem? How much noise and inductance can there be?
