Hi LASERS!
It's just since I was a child that I would own an argon laser...
I was fascinated by a '90s pseudo sci-fi movie where there was one in a lab, lasing and reflecting all around the room, with this beautiful azure color.
So, many years later, I bought one piece at a time and I managed to assemble it.
But now, I need help among you savvy, since I couldn't find (or interpret) any info on SAM's laser FAQs to help me on making it work correctly.
Let me jump straight to the problem with some details:
The model: as per post thread title - JDSU 2214-30SLQTA.
The PSU: JDSU 2110U-MLS.
The cooling system: Original duct pipe; so, present.
The problem: LOW output power, almost none, not a real change between Light/Current mode switching.
Suspected PSU incompatibility.
Help me please, maybe I should modify the 2110U-MLS PSU : ).
More details will follow with some pictures, a video, and measurements below.
24 ~ 54 VDC: DC+
-115 ~ 138 VDC: Cathode/Filament (F1/F2)
14.6 VDC: +15 VDC
-14.9 VDC: -15 VDC
14.0 VDC: Start+
0.0 VDC: Start-
Descriptions under each media:
This is the working behaviour of the laser.
You can hear the clicks of the PSW, everything looks normal as described in the SAM's FAQs.
The Yellow channel in the oscilloscope is the DC measure of the POWER output, the Blue is the LIGHT output.
When I switch between the two modes, the power rises because the pots are set one to 5k and the other to 100 Ohms; I see no noticeable difference if I invert the pot's settings.
The general picture.
Note the starter circuit box is open, I did it to see if I could measure something.
The laser head, removed from a KLA Tencor optical inspector.
My control panel. The umbilical cable connectors where open for a general check.
No difference if reassembled.
This is the scope measurements in low power, all the pots at minimum.
Yellow is POWER, blue is LIGHT.
This is the maximum I can get.
For the sake of reporting.
Well, that's it for the moment.
I hope I will get help from you soon!
I am anxious to make this beast work : ).
Thanks and have a nice day,
Dario.
