I have a simple SMA fiber input fitting and one to hold your PCX housing. I am being careful NOT to burn another
expensive component. The fiber cable should protect the FAP if something goes wrong. I will be cleaning all optics
before I bring up the 808 power!
Those are coated lenses from THOR Labs. 26 mm OD and 16 mm fl Aspheric PCX.
Not been able to log in here for years for too many reasons.
1. I looked into adding CC to your PTH08 supply via the tracking pin by adding simple add-on circuit. Difficult because TI Datasheets seems to hide the glue switching chip, incomplete schematic shows no inductor! There must be a simple way to adjust current via over current also. I'll let know latter on that. I really love the boards state of the art inductors. I'll post my solution on this latter.
I would use only 16 gauge wire to FAP as over current insurance and add
super low res. capacitor solders to FAP pins. PM me and I'll mail you a free diode protector.
2. Inside the FAP, what's the layout, bar or separate diodes?
Any photos posted here?
I'd like to interface my new 40W bar with fiber concentrator and found one on e-bay, do you think this is near same what you see inside the FAP.
I need homogenize my bar into a 3x3 crystal, I think this one perfect.
see attached link.
I found a good document on that regulator and forwarded it to Mike, he probably still has it, but I don't. It isn't a schematic regarding the IC, but does give a pin-out and all the info you might need to make one work.
I have bought both bars and FAP units with a bar in them. As far as getting the fiber bundle to put on a bar, you can do that by buying one on ebay, but not cheap.
I Know it's been a year but I have worked on other fun projects
like my Phaser and NdYag. I'm now trying to get this 40 Watt FAP
As in previous posts, I have started using a Coherent fiber cable to
smooth the 19 spots but all my previous attempts used small optical
assemblies which proved awkward.
I now have a neat little optical "bench" so I can try different lenses. The mounts slide
inside the channel which is made of PVC pipe. I currently have an output
lens with a 39mm FL DCX lens for the objective.
I have the FAP limited to threshold, about 15 Watts, and can't seem to get a tight spot
greater than a distance of 1.5 to 3 inches. I'm looking into a PCV lens for the input now.
Alaskan -- I'll also be looking for a larger 400+FL lens for this.
When viewing the output of my own FAP laser (without that piece of fiber attached) using that same model of SMA coupled lens, that lens collimates the output, it's a high mRad, but appears collimated, you can see what the beam looks like shooting at a tree in my avatar. To focus to a spot you may need to replace the lens in that holder with a negative FL expander lens to expand the beam and then put a PCX lens in front of it to allow variable focus. That's what I did, but unfortunately, that little SMA lens assembly had its lens glued in and it cracked when removing it to insert a 12.7 mmm concave lens in its place.
