I'm sure this has been posted on around here before in the past, but this particular link has some interesting information on wavelength and other peramaters: Boeing Completes Preliminary Design of 100 Kilowatt Free Electron Laser Weapon System and Eventually Megawatt Class Lasers Another...

Found this article a few minutes ago, a brief history of the development of the laser (incidentally it's 50th anniversary will soon be upon us!) from Baylor University in Texas. Baylor University || The Lariat Online || News "Some colors that correspond to waves are easier to get," Olafsen...

Very nice! I especially like the third pic with the greenie and diffraction grating. I never get tired of diffraction grating laser beam pics. Speaking of lighters, I had an old Zippo that belonged to my father, he got it (I suppose, he's dead now so I have no way of knowing) when he served in...

My Ebay account got hacked a few years ago and I found out I had several laptops for sale that I didn't know about. Every time I tried to kill one of these phony auctions another would pop up, like pulling weeds and having more sprout up in their place. Luckily I got Ebay to cancel the bogus...

There's no way you could have something like that in your home, at least not if you hope to power it up and run it. I'm almost positive you'd need 3 phase 480V + a separate cooling apparatus of some sort to keep it from overheating. As for what is possible, lasers like that can cut thru a few...

If they're talking gamma rays they aren't talking about lasers....perhaps (if there is any truth behind this tale) some sort of nuclear device could emit gamma radiation and kill someone (actually that really happened to a spy in Russia a couple of years ago - he was exposed to some sort of...

I think the reaction depends as much on the type of animal (and its age) as to the color and power of the laser dot. I have 5 cats, 4 indoor and a semi-feral outdoor cat (long story on that one, basically a female cat that had kittens under my tool shed and I adopted 2 of her litter, gave the...

U.S. Army Selects Northrop Grumman's 100kW Solid-State Laser for Field Tests at Its High Energy Laser Systems Test Facility Who wouldn't want to see some burning action from a 100KW DPSS laser?!?!

Actually that show was on the History Channel and not PBS.

I'd be very happy if all the mosquitos would just disappear - by whatever method of eradication! My neighbor got lyme disease from a mosquito bite (he was way out in the woods somewhere chopping up firewood, not around here) and he has been suffering from the aftereffects for years! If not for...

Just make sure you don't eat any yellow ones lol! Thanks for the compliments, everyone!

I made a video of some still images I took of several of my lasers shining on these huge icicles that are hanging off my back porch (405nm, 660nm and 532nm, some mixed together): YouTube - lasers in ice.avi

I saw that on tv a while ago, pretty cool.

Frying bugs with lasers might be fun sometimes but it doesn't seem like a very efficient way of destroying large populations of certain insects. Compared to most pesticides it would certainly be better for people and the environment, but it still seems like a lot of effort and complexity is...

I used a 514nm green single line argon, and a 660nm red diode laser module. I was going to use one of my 488nm argons but they just weren't bright enough to "compete" with the red (which is supposed to be putting out 150mw, but I have no meter to verify that).

It would be interesting to see a video of that...would make the average match lighting video you see everywhere look like nothing! (actually I did just find a video, but not very exciting.... http://www.wired.com/dangerroom/2010/02/laser-jet-blasts-ballistic-missile-in-landmark-test/

I found out back in 1997 when I signed on with a temp agency (was unemployed and desperate, not the sort of work I'm cut out to do) that placed workers in industrial jobs. They first had me at a packing plant and when that job was over they placed me in a laser machine shop. Just the luck of...

I think it is also nature's way of making even more of a fool out of Al Gore! BTW it is snowing heavily here right now and there's a huge (like three feet long) icicle hanging off the roof on my back porch and it's a very tempting target for some of my lasers!

I'll ride just about any rollercoaster or thrill ride - to answer your question, yes. You might want to look into joining ACE - American Coaster Enthusiasts. I'm a card-carrying member and have been since 1997. I have ridden over 125 different rollercoasters in my lifetime. Here's the...

I had something like that happen to a brand new rechargeable AAA battery that I was using for some of my pointers. I had two of them and had them (luckily!) in a cheap 1m red pointer and all of the sudden the laser got real warm and just like you did I took the batteries out and one was real...
