It's Nd:YAG/NLO, cylindrical medium, side pumped. The beam diameter is just the nature of the design. You can get narrower beams but don't forget to write the check for twice the amount. This unit is to be used for university education so it's really a demonstration device.

I was dealing directly with Beyond Productions, their production company in Australia. I think Grant would have been geeked to run a big laser himself. I was going to haul them out but I gave them a huge list of safety requirements to operate the lasers at M7 where the build team works out of...

I wrote a treatment for the use of lasers in the episode. They wanted to use my 35W YAG and a few others I have. Turns out there just wasn't enough to justify the expense. They really wanted to pop a lot of popcorn with a laser just like in the movie Real Genius which was they myth they were...

@jander6442 - Yes that is Hill Dog You can see another that used to work in the office here (aka Dozer): vR1Tl7SM4J4

Apparently they don't like the music.

Good catch magonegro. If the pulse was 10ns you would be right. I just pulled the test report on the laser. I figured out where the numbers came from. It's the rated output I posted and the pulse duration should have been 100ns. That's what happens when you edit video after midnight. The actual...

Here's a 1.1mJ 532nm Q-switched DPSS laser system I got to play with. It's water cooled. I wish I had more time to work with it. The video was kind of made on the fly using whatever was around the lab. jTRSKOO0-BQ

I ran a calculation the other night I was going to post but I lost the post accidentally clicking on a link. In any event, a person can see about 100 photons and be able to identify it. It is possible to even see one but most people don't recognize it. I figured a one watt 445nm would give you a...

Output from a 532nm is absorbed all the way to the subcutis layer. This layer houses larger blood vessels and nerves with smaller vessels in the dermis above. Blood absorbs 532nm readily with a peak absorption in the 600nm range. Thus the blood vessels are being burned or heated to levels to...

Hey everyone. I hope you all have your laser eye protection now with the possible exception of our overseas friends. Now that the group buy is complete I want to thank extelon, daguin, and scopeguy for their hard work in getting everything arranged behind the scenes to make it easy for those who...

@Dave, you get pretty good at building those things fast after the first few. I don't know how many we go through in a week but I'm glad I don't have to build them, lol. At least you don't have to build the big boxes. We have a 28 laser order shipping soon going to one of the gov't agencies...

The protective eye wear has all shipped to Dave via FedEx Ground (863799415000255) less one pair that was picked up locally.

Yes that was me. I have returned to ensure those purchasing protective eye wear get the real information they need. I have posted on a thread or two mainly because I check in to answer any questions on the group buy and some thread or another grabs my attention. I have no intention of rapidly...

The active portion of the lasing medium and non linear optic is a function of the beam waist of the pump diode as well as the cavity configuration. Flat mirrors for example will output a much wider beam whereas a hemispherical OC will output a narrower beam because the light is refocused into a...

Just FYI, it looks like everything will ship to Dave on Wednesday. In the worst case it might be Thursday.

We just sent out the quote to extelon. He's been working hard on this so I imagine you will be getting your prices soon. @Dave, we will get the shipping extras sent out to you once we get your address before the filters arrive.

Re: GB for OEM Laser Systems protective eyewear Exactly 25 units is 20% discount plus free shipping to whomever is the organizer. No matter what the actual number of units we will ship free to the organizer. The best percentage discount is 26+. The actual order will not be via the website so we...

Re: GB for OEM Laser Systems protective eyewear @extelon, Once you have the confirmed list of filters and frames send the list to me. You have my email address. We will return a formal sales order with everything listed for your verification. Then we can forward an invoice for the total amount...

Re: GB for OEM Laser Systems protective eyewear The reason I don't run it is twofold. The first is we the supplier. The second is I don't have the time to run the GB. See below: We are happy to assist by providing discounts. Those discounts are offered because we do not have to pay anyone to...

Re: GB for OEM Laser Systems protective eyewear Because we added the 7.5% discount to help if you couldn't get 25 pair, the percentage does indeed work out to a 22.5% discount if you order 26 or more plus free shipping to whomever is the organizer.
