Scientists drag light by slowing it to speed of sound Not really sure if this has been posted here but I found this very cool. Basically they slowed a green laser by shining it through a ruby rod spun at up to 3000 rpm, causing the light to slow to the speed of sound they say and redirecting...

I've recently noticed a "hole" down the center of the beam of my 445nm build using an A140 diode in a JayRob host. When I first noticed the "hole" I also heard a slight jiggle and narrowed it down to the lens assembly. Turns out the retaining ring on the back of the assembly had come a bit loose...

I don't have any of my own 445 pics yet, still working on getting parts for that build, however a lot of members here do. I've seen a few side-by-side pictures of 445 and 405 and I'm pretty sure just about everyone here has seen wickedlasers video of the sonar and the new S3. Whata ya say we...

I just finished my first 6x BR and I've just got one question. When I tested the driver I built for it with my test load I used 7 1N4001 diodes becuase that gave me a 4.9V drop and the SF-AW210 gives a 4.8V drop. Anyway, I was using the lm317 driver like I have many times before so nothing new...

I've been looking for an affordable high power IR c-mount for a project I've got planned for the near future. There are quite a few on ebay. Is there any reason that members here use 808nm diodes more than anything else or is it just that they are more readily available. Now from what I've...

I'll have some pics up tomorrow. Well for starters, the only other green laser I've had before this was the 75mW phoenix from WL. I realized about a year after I bought it that I had paid to much lol. Anyway I love the price of the 150mW module. $101 shipped is great. I also love the power...

I just had surgery on Friday, so I've been stuck at home in a bit of pain lol bored as hell. So to ease the pain of boredom for the next 4 weeks or so while im stuck at home, I've got some parts coming for my own 7 color. So I was looking online at hobbypartz.com just seeing what kind of motors...

My uncle is a gun collector and way back when he bout a 5mw red laser sight for almost $300 for his .44 magnum desert eagle. While I was visiting him we started talking about lasers and he asked me if I could do anything to make this one brighter and possibly a different color. Now the entire...

How exactly do boost drivers work? I've been curious lately and i want to be able to drive a red or BR diode with the power from just 1 18650 or other 3.7v battery. i would also like to have the ability to control output like with the lm317 drivers I just also want to be able to power it to its...

In the past I've either bought my laser diodes already removed from the sled so the ribbon was already removed or bought the sled and taken the diode out but left the ribbon. In order to make my future builds neater and cleaner, i was wondering what is the best way to remove the ribbon without...

First off, forgive me for asking this lol I know I have seen it somewhere on here I believe a few days ago but I've been searching for 2 hours now and can't find a damn thing. SO my question is how can you use a pot other than the one on the stock driver for greenies to control power like on a...

I just got back from the concert in the gardens laser/firework show. First off, it was an amazing show. Concidering that this was one of the only laser shows i have seen I cant really say weather or not it was a really good one or not, but I thought it was da shiznitz haha. I was wondering if...

Ok so I'm still very inexperienced when it comes to electronics and I've got a few questions for anyone that can help. First off, for a capacitor, it does matter which way the current is going through right? I mean there is a + and - side. On the 10mfd 16v one i got the pins are the same length...

I saw this video and according to the guy doing it, he was running the diode at 600ma... does that sound right? Please watch this and tell me what you think. http://www.youtube.com/watch?v=B2mEpnogUMI Thanks

Hey guys. I made a mistake and kind of posted in the tutorials forum before i said hello. Well hello!. I've been into lasers for a while but I recently got interested again when I saw Rog8811's white laser. Soooooo I'm thinking of trying to build a few small simple lasers and eventually try for...
