I have recently discovered an interest in laser pointers and what I might be able to do with them. Experiments in light come to mind.
So, I found a set I liked, ordered them, and am patiently waiting for them to show up.
Until then, I have a spare part laser I got from an old laser level.
It works fine powered by either 2 or three AA or AAA sized batteries. (Although the original housing was designed for use with 2 AA batteries.)
My questions. How do I know how much power my laser can handle?
And
If my 3 AA batteries equal a combined voltage of 4.5v (No info re:amperage)
Then, can I use a "phone wall charger" that outputs 4.5v at 0.5A as a "fixed" power supply? (Ps. this would then be a stationary device)
I ask because I tried it earlier, but the laser did not come on. I was afraid I had burned something out, but when I used batteries, it came back on. Is there perhaps some type of voltage regulator that might shut off the power stream? Or might I simply have not been making good contact?
Any help would be appreciated.
Thanks in advance,
