Khamien - did this happen from 'minute one' of the build, "out of the box" or something that happened gradually? You don't happen to live in a humid environment do you? I'm with Infinitius on this, but the reason I ask is, in humid environments, with my cameras, i've had to deal with 'lens...

Hey Johnny. Welcome. :) Mac's tips above are a good kind of 'guide' to start by. What got you into lasers?

Eh. sometimes to kill time (I haven't been around lately due to real pressing family tragedy stuff) - i'll sort newest and answer legitimate newbie questions even if they aren't phrased quite right. While yeah, search is important -- I've even had trouble finding posts that I *know* exist on...

Aha RHD! Ok, that explains some of it. I've been 'gone' as well, dead computer and death in the family. (big sigh)... Getting back into the game here, myself, as well...

I've got a Hughes tube and PS from 1978...

Oh, I do remember those. Edmund Scientific sold them in the late 80s, and yeah, they were $750. In the late 80s. Red diodes were $300 then too. Indeed, times do change. Still kind of an interesting 'near he-ne pointer' and a green one at that... I do believe GreeNes are getting scarce...

From my research, Cheech? Pretty much nuthin'. A tunable HeNe maybe. :P Or a straight 604nm.

Cheech let me know what comes of that, and if you are/arent arranging something with it?

I run the tunable for an hour a month, sometimes more; I actually have its run-in scheduled into my Outlook calendar for the forseeable future. And yeah it's the second 612 in my sig... It does 633, 612, 604, 594 and 543. The real bummer about the tunable (besides its cost) is that it's a...

Heh, does my tunable count as a second? :) You can turn a knob and make it into a 612 for the time being. :)

Part (most) of me wants that 612. Another part of me feels real bad about hoarding the only known 612s this side of nowhere, and I kind of want to give someone else the opportunity. That said, if nobody wants the opportunity, please let me know. Dave--- I will take it if nobody does (very)...

Unfortunately, the reason they do this, is the same reason most 'sales reps' require you to get a "quote". First of all, let me just say, even in business, when i'm doing "b2b", I can't stand this. If I need something, I dont want it to "be sold to me", I want to buy it. In other words, I do...

See, I usually put in weird-ass numbers. I'll bid like 56.83 on something, or 78.87 -- I figure other folks are sticking to more 'round' numbers, I have no idea if it works any more for me than anything else (I'm sure there are statistics that say it doesn't) -- but it could just be...

Bloompyle, I do pretty much nightly searches for: "JDSU Laser" "Uniphase Laser" "Melles Griot Laser" "HeNe Laser" "488nm Laser" "Cyan Laser" "612nm Laser" "Orange Laser" Then I sort by most recently listed. That's my "secret", heh. So something like this, I'd see it right when it was...

Yeah, some people are gonna be angry at me for lucking out like this... A discliamer first, I rarely "luck out". As some vets here can attest to, I've had more ebay losses than wins. I have a pile of "dead soldiers" I chalked up to a loss, and the 'tuition price for learning'. ArIons, HeNes...

What I've found is -- the higher power the yellow DPSS, the more stable it is. If you can get something ~50mW, it'll likely be pretty stable. Under 15mW, not so much. That's my experience with 7 DPSS yellows... I'd also go with PGL, the GLP 589s seem to be notoriously unreliable. On the...

Not really possible to capture on camera. A lot of folks say the difference is not visible; and that the only differences I've seen are due to power. I disagree with that; I have a 15mW and 50mW 594, and a 5mW and 90mW 589. In all cases, at least to me, side by side and even alone, the 594 is...

Yup, isn't that called the "walking ghost" phase of radiation poisoning? When someone has gotten a lethal dose; the initial burn/vomiting/fever etc effects have worn off and the victim feels fine for a while (even like they have completely recovered) -- but their intestinal lining and blood...

I should check back in a year or so and see if you have any openings.... My response: what others said here. Looks like I'm late to the party again :P

Had this exact thing happen a week or so ago. Called them up and said "uhh, it's a refund, why is it on hold" - the guy made up some blah blah about bank accounts, and the next day the money was back in my account. No idea if it was due to the call or not, but may be worth a try.
