Hi ppl,
I've done a lot of searching and reading before posting this, so please bare with me if this have already been answered somewhere :/
As fa as I understand (I'm newb on LD's :can the driver for a LD is for protection of the LD through securing constant currency delivery to the LD.
So far so good
So, my Q is this:
If I use a bench PSU with build-in CC (constant current), would that be suffecient protection, ie does it do the job that drivers are intended to do?
If so, I understand that switch mode PSU's are more elec noisy - is a linear more recommended?
( ARGLaser: http://laserpointerforums.com/f67/first-power-supply-80274.html )
I "suppose" the ripple should be around or less than 1.5mv?
I bought a pigtailed Coherent LD 2W 835nm, 2.8-3 V. at 1.5 A and intend to use it with a PSU for smaller engraving.
Would be very nice to just be able to connect the PSU and be ready to go
Also, in near future I'll be building the "pocket CNC" (using other LD's) in which Arduino control circuits will be used - so I'll be going for a 2-output PSU
Thanks in advance!
Great day to you all
