general purpose optics equipment?

how is a HP current source power supply for laser diodes?

I don't mean a PSU used as Current source, I mean a "current source"

I think their mad well built. Its like a harrison supply got put through star fleet boot camp

I just need to hook up a oscilloscope on very fast time base to see what happens during power up on various loads right? maybe some power LED to simulate the laser transfer function etc

DavidKo:
For laser drivers is most important not to overshoot the current. The laser diodes do not like it.

Well I got the Thorlabs UV glasses.

I can see more and they block way more then the China glasses. And the are 10x more comfortable.


I see if you wanna work with a laser correctly, you should get band specific goggles for the frequency you are working with.My suggestion is to take it slow, save money and buy the optimum safety equipment. Seeing more makes the work more enjoyable and pleasant also. As usual, trying to be frugal ends up making you feel like the victim of a joke.


same as butter knives, you don't wanna be using the plastic butter knife from macdonalds to make toast.

Once more proving the universal truth.  Labor can be substituted for capital, but sometimes the amount of labor is astonishing and/or unbearable.  The right equipment makes any job easier and safer.  The other thing that has been demonstrated here is that the limits on capital are always fuzzy.

Conrad Hoffman:
You might like looking at back issues of Laser Focus magazine. Lots of lab setups shown. When you see something that looks similar to what you think you need, it's usually not hard to figure out the specifics.
