    New FDA "pointers" regulation page published today 05/14/2015

    Hey Encap, thanks for posting this, and also for linking to the FDA page at the end. I'm glad to see that they are still focused on the manufacture and sale end of things, rather than crossing that bridge into ownership and possession territory. I believe THAT would be serious overreach. Do...

    Re: new to laser tech and have a unique question Ya know kurt, the members here aren't idiots. You may think that you were being cleverly vague and evasive in your description, but anyone who's even casually paying attention knows EXACTLY what you're "cooking up". Did you really think anyone...

    different types of laser lenses

    The lens doesn't matter. If you want your laser to go really far, try Priority Mail International. :yh:

    Re: new to laser tech and have a unique question Given the fact that you completely understand the mechanical function of a laser and are not a complete noob, I'm sure you are aware that this is a tall order. And being limited in funds makes the task particularly difficult, because initial...

    Hey everyone, I need some help calculating wavelength for my next project.....

    I've been working on the design for awhile now, and was hoping to keep it under wraps until I had a working prototype. BUT, I need to get the math right before I assemble the cavity and configure the active medium. A few preliminary details: The active medium is going to be a matrix of a...

    What is the wavelength of true brown?

    I AGREE!! They TOTALLY SUCK!! We should get RID of ALL monitors NOW! Sorry, I just HAD TO....:) Anyway, back to the brown laser- A bit of laser trivia for those curious about brown laser theory and practical implementation: Q. What is the most common excitation mechanism for a brown...

    Apologies

    See that? You're already sounding more positive today! I wouldn't worry about anyone here feeling snubbed or anything even close to that. If anything, I believe most here figured that you had a bunch of "stuff" going on that couldn't be avoided. It happens to us all from time to time, and...

    Assistance appreciated!

    Hey SBA, Which stars are involved in this? :tinfoil: I'm thinking possibly Tom Cruise, John Travolta, Kirstie Ally and (of course) Shirley MacLaine. As pre-ascended entities, these four are the IDEAL conduits for our communication with those occupying the eighth astral plane...

    looking for beam expander for 3.5W 445

    Hi SSS, That max. power rating sounds a bit low to me. Can you give us some links to the products and specs that you're talking about?:thinking: Regarding their use with multimode beams, I don't see any issues as long as your beam dimensions don't exceed the maximum input beam diameter...

    pics of my new build :D

    Hey, cantthinkofone: Those are some really nice beamshots. Especially nice I think is the quality of the color that shows through. Many times, correct color saturation can be lost in beamshots, but yours are very nice in that regard. Nice work!!:beer: On another (and somewhat goofier)...

    The Death of the Mighty Steed

    Hey, SBA Sorry to hear about the loss in your family. BUT....on the bright side, at least she didn't die outright and leave you and your daughter stranded. And also good is that it didn't happen when wife or daughter was depending on reliable transport alone or at night. That's a good...

    A eBay laser (be nice)

    Actually, it WAS a nice edit. And, in point of fact, I DECIDED (prior to any response to that post, BTW) to edit because I reconsidered my original tone and DECIDED to cut you a little slack here. The fact is that you are asking an asinine question about a super-cheap laser that is produced by...
