So I finally got my first gas laser... a simple 0.5mW 632.8nm Melles Griot HeNe off of eBay. It's a 05-LHP-214, with a Laser Drive 106T power supply outputting 1250V DC@4.0mA (input 12VDC@1.5A). Now here's the interesting part... the laser powers up as soon as I plug in my charger for my PSU (a simple wall charger off of Amazon that ouputs 12VDC @2.0A), stays on and stable for about 15 seconds, then flicks off, sometimes sputtering a bit. There is a very quick arcing/sizzling sound when the laser flicks off. If I short the Alden connector and then plug the laser back into the PSU, the cycle repeats.
I haven't been able to find any power requirements on this particular model, I'm wondering whether this power supply is feeding the correct amounts. The laser is about 177mm by 31mm, and by my research is quite similar to the 25-LHP-213 offered by MG right now. However, I can't find any info on that laser either, other than the fact that it uses "Power Supply Type A" :thinking:
Since I bought the laser and power supply together from eBay, I thought the PSU would match the laser... and if so, what could be going wrong?
Thanks so much :beer:
I get to enjoy glorious 632.8nm light at 15 second intervals :na:
EDIT: Oh and my HeNe is a laser head, if anyone has a (bare) laser tube and power supply, or a (bare) laser tube that is compatible with my power supply, and he/she is willing to sell it, I'm interested :beer:
