Title says it all. Got my 612nm HeNe out of its tube successfully. I eventually managed to heat it up slow enough, without damaging the tube to use aluminum sheet metal (roof flashing) to cut through it and push it out. I can finally get to work on fixing this beast once I get an LPM . But that's likely a ways off. On another note, it's a beautiful tube and my patience getting it out has rewarded me. Lots of plasma is visible as per usual with larger MG tubes, the bore is not frosted like many of the larger tubes but it does appear to have a rather wide bore. This must be how they managed the higher power while keeping power requirements down.
I can breathe easier now, but on that note. Pretty pics of this fiery beauty!
Bare tube at last! after much picking over, and trial and error, I finally got this stubborn on out. It was much harder than alot of smaller heads, and had pretty liberal injections of hot melt in it.
Note the relatively wide bore:
What a Firey orange!
Looking closely at the dot, you can see its gaussian, but its faded ever so slightly in the center, making it a more 'taurus' like beam, but not completely the infamous 'doughnut mode' this suggests the reason for its low output is misaligned mirrors, though only slightly. or an overly large bore for the mirrors. shame as this is (as far as i'm aware) the most powerful orange tube ever made sitting at a spec of > 4mW up to 10mW. perhaps with some tweaking I can recover some of its power.
