Hmmmmm, tough question. I enjoy ANY monochromatic light, though I suppose I do have some favorite W/L's. In the red range , I still love the 632.8 HeNe line. Though, I may be influenced by the inherently high beam quality of HeNe lasers. I just love those gas laser beams. In the green...

HA! Nicely played. Actually, on "rare form" days (and post-coffee) my "potty humor" is much more subtle, though sometimes more profound. On normal days, I'm at a complete loss for potty humor. Just brain chemistry, I guess.... -mega

I could be mistaken, but your choice of words sounds a bit accusatory. (as though you doubt the existence of any "legitimate" reasons that anyone may have for owning a laser) Thanks to a relative few morons out there, laser enthusiasts have gotten a bit of a bad rap lately. The news media's...

Is it mere coincidence that Infinitus posted the :toilet: , and now we're discussing a "basic process of elimination"? Or do I detect a theme? Anyone?..........[crickets in background]....... OK, nevermind. Sorry, adolescent potty humor's all I got this morning.:D I haven't had my coffee...

I was just cruising back through this thread to see if I missed any good questions, and I noticed this. That's the funniest damned thing I've read all week! Thanks man! Nice job with the dry wit... I actually saw some of those combination LED/Laser diode units at Home Depot, and I was...

I don't need any, but I just wanted to comment that it's cool of you to offer something back to some members here. +1 from me just for bein' a decent guy.:)

Not a problem. Don't give it another thought. BTW, CJ: I apologize if I came off as being "preachy" about other folks being out of work. That's not how I intended it. I only meant that despite the crappy economy and job situation here in the States, you got a job that you can be excited...

I wasn't referring specifically to anyone here on this forum. I only meant that in GENERAL there are many folks out of work these days, and CJ208 is fortunate to be getting paid to do something interesting and enjoyable.

Hey, thanks for the kudos, Lasersbee. :yh: I have a few things to add (I was a bit distracted last night). If you have two of those beamsplitters, then you don't really need a second, lower powered laser at all. You just use one of them to cut the beam power so that it is within the range of...

Okay, the first thing you need to know is EXACTLY what your optics are doing to your beam. In other words......You absolutely cannot assume that your 50/50 BS is actually 50/50. There are VERY FEW beam splitters that are flat across any real range of wavelengths (and they are VERY expensive)...

DUDE! That is supremely cool! You're 16, and you work for a major optics supplier. How cool is that? Congratulations man! Do tell.........how did you come into this job, and what do you do there? Look, I don't care if you're the new CEO, or you sweep the floor in the warehouse after...

Very cool indeed. I'll have to check this out for my area. Thanks, sopark4000!:) +1 from me -mega

Yep, ya got me on the coconuts.:scowl: Regarding the etalon, I was kinda hoping Gofilord would do some research and take a stab at an answer. Anyway, the finesse of a Fabry-Perot etalon is a measure of it's resolution. That is, it's ability to resolve closely spaced lines within it's...

Depending on materials, and who made it, it's possible to spend north of $1K on a quality hand-made blade. Now you have my curiosity piqued. Can we have some info on your (soon to be) new knife, joshshermannn1? Knives are one of my other interests. Thanks.............-mega

I was thinking along the same lines as AJ DUAL, so I did a little digging and found this pdf. It's not the same exact part that you have, but I'm betting it's very similar. Notice that the laser output is only 300μW absolute Max. rating, and only 180μW typical at 795nm. I don't know if this...

Whoa! That's impressive. And I thought the only reason for huge hunks of metal was heatsinking. Evidently they're also good insurance for when your laser decides to go all "road warrior" on you!:D Looks like your lab laser really doesn't need to stay in the lab. Hell, with a couple of...

Re: Added info to make reviews acceptable on LPF... Hi Dave, I just wanted to say that you make some excellent points. There are considerations beyond the obvious, and they are not necessarily recognized by the average buyer. Anyway, I just wanted to add that. There needn't be a an...

Dammit, midias! ........ Beat me to it! Okay smarty-pants......What is the airspeed velocity of a COCONUT LADEN swallow?? HMMM? :na: Typically, 1.21 (Though the Gen-2 units in development are rumored to be at least two orders of magnitude more efficient.) WOOHOO! Roarin' 20's, here I...

Hey CJ, Edmund's is okay if you REALLY need a specific lens or other optic, and just CAN'T find it anywhere else as surplus. That's mainly because they're a commercial supplier, and don't market to the DIY/hobbyist crowd, and as a result, they are expensive. I have ordered a number of...

Thanks for the +1 Ghost (and FTM, thanks to Misanthrop for the +1 the other day). Misanthrop, which optics are the polarizing mirror and the λ/4 plate? I'm thinking the λ/4 plate is the piece in the "squarish" mount just above the quarter. (just a guess). Thanks for the info. +1 Misanthrop...
