There have been several optical trapping threads recently, but I thought I'd put one in the "Science" category. YouTube - Optical Trapping I have a full write-up and some highish res pics here: Optical Trapping and the Momentum of Light @ JWC.blog

So I've been planning to build a green labby for quite some time now. I bought some crystals from BlueFusion back in July (big, unbonded, and pre-rotationally-aligned) and I'm pretty excited to start working with them. The cool thing, at least in my mind, is that it's going to use a...

Scientech 372 Laser Power Meter @ JWC.blog This is a copy of the post on my blog about the power meter I got from Laser_Ben this weekend. I apologize for any errors during copying. This meter has a thermopile detector (as opposed to the photoelectric sensor on my Liconix 45PM) and can measure...

Well, my summer is now officially over... Classes start tomorrow. I thought I'd celebrate a little bit. Large size pics are here (click on them): Random Laser Pictures My top 2 favorites: Also, I built a simple carrying case a few weeks ago. It still needs some polishing (better foam...

Using 3 hosts from Ehgemus, I created (or rather, am creating) a matching RGV set as my last portables before I move onto tabletop laser systems. Unfortunately, the driver for the red diode isn't working as I expected, but I have the green and blu-ray up and running. Lots of pics here: Triple...

Here's the condensed version. About 3 months ago, there was an accident involving a ~60mW 532nm laser and my eye. Exposure time was well under a second. I went to my optometrist a few weeks ago for a routine checkup and mentioned this. After yelling at me for not telling her sooner, she took...

Story and more pics @ http://blog.jwcxz.com/?p=368 But yeah, I'm going to wait for my TEC to arrive before I go any further.

This might be gone by the time you see this, but today's Woot is some AA and AAA batteries plus a charger for $9.99 + $5 shipping. Not a bad deal.

I'm surprised LPF doesn't have one of these...  Let's start one! Here's what my desktop looks like this month:

I discovered that when I burn through a CD case with my 300mW green laser, the following effect is produced on the wall: Full pic: http://jwcxz.com/projects/lasers/halos.jpg Video: http://www.youtube.com/watch?v=Wy3oR6fY6W8 At first, I didn't know what this was caused by, but I found this on...

I've been researching, measuring, drawing up plans, redrawing plans, re-researching, re-measuring, redrawing up plans enough.  It's time to start building this thing. I've put up the first post of my build log on my blog: http://blog.jwcxz.com/?p=270 The host I'm using is only labeled as "MX...
