give cavity extender and etalon pls 🥺

you can do it through google maps. its kinda neat! https://support.google.com/mymaps/answer/3024454?hl=en&amp%3Bref_topic=3188329

maybe start a new thread? :P i've been looking for fellow laser people near me but have had no luck :/

the one i tested was rather low but i'm not sure if mine was just defective. I picked up a cheap sanwu striker and it started out around 435nm and settled ~440nm doing the full 7.5w. this is the only nubm44-v2 i've had and tested so i'm not sure if this is standard. color looks identically to...

some steal wool does the trick :P

the spectrogard ones are lovely! i briefly had two pairs but it seems they are very rare.. i've only ever seen 4 in existence including the one in your archive... they are great for ion lasers :) did yours have some sort of crud on the back side of the filter? both the ones I got had the same...

pricey but perfect imo :P Voltex supplies are the best.

i gave one to a friend who was meaning to put a 6" orange HeNe into it but i don't think he's gotten around to it. i can ask if he still has it for you if you'd like.

if you find a big old lyte pointer they work great for 6" HeNe hosts. stick a 2 lithium cells in with an voltex A-14-00 and you're good to go.

just wondering if anyone has an omni 543 head with decent life left that they're willing to sell/trade?

how'd you manage to get 594? I've only been able to barely squeeze out 604 but not anything stable.. I believe the prism is only coated for 632.8 and 612 and my OC really only does 632.8.. i have to use a second krypton ion OC on the output to get anything else

one, you'd need an entirely different power supply if you were to do that. two, you'd need a precise gas ratio of about 7:1 HeNe, pure and expensive isotopes of both helium and neon and like said above, a ton of patience. you'd need to smash the outer envelope and water cooling jacket to install...

thats not the proper way to do it. first off, you'll ruin the goggles before your power meter has time to measure them, and the OD increases dramatically as they char.. even at low powers, you won't get an accurate reading. you need a proper spectrophotometer. and i'm guessing this guy doesn't...

well its better than being blind forever :)

they can do good but, theres been some recent tests where the OD below OD3 for OD6 rated goggles and the 15-4 IR goggles dont even reach OD 1 for the MAIN yag wavelength... they can do good but the inconsistency and lies about specs make them untrustworthy. its ultimitely up to you if you want...
