Pics and particle trapping with first build

[ChaosLord]

I finally got a few (bad) beam shots and a couple of vids of my first build.

Build found here: http://laserpointerforums.com/f50/first-build-650nm-300mw-81263.html#post1166739

Of course the first thing I did with it was... Particle Trapping!
I also discovered that almost dried out wire glue is great for this. Once my bic sharpie alike stopped working, i got an idea. I took some wire glue I've had for awhile, witch was almost dry (kinda tar like), and dipped the marker in. If you look close in the vids, you might see extra "crud" on the marker tip. Thats the wire glue. Got the best particles trapped with it. Now just need LPM!

Thanks for looking! :beer:

Very nice videos and congrats on your first build how about some pictures of the laser/build :tinfoil:

Particle trapping isn't easy the first time you try it, good job :gj:

Thanks. I was shocked i got a couple on my first try.

I put a link to the built thread in the OP.

Particle trapping with 650nm ~300mW 2nd build

Well, since my Bluefan LPM seems to be in customs limbo, I thought i would share this here. I was going to wait until i review the build, but want to wait for the LPM. I got this footage with my second 650nm build, best trapping I've done yet. I couldn't wait to share, so i updated my thread.

This build has the same DTR 650nm module as my first built, as well as a mohgasm linear set to 378mA, just like my first one. The biggest difference is that i put it in a c6 host with aluminium heatsink, and the driver is round.

This is what I got last night with this build. It seems like a perfect combo for optical/particle trapping.

If my focus adapters fit the lens, I would have moved it up and down the beam.
But moving a particle with a beam of light is still awesome!

Incredible, I have to try that sometime....still don't understand how it happens.

Okay, +1 for intriguing the hell out of me! I have been playing with lasers for a long time and I have never done that! To hell with le duty cycles!!!!! JK

Lol, yeah I have started to get a little nervous when they won't die, and the laser closing on or has passed two min.

I did seem to heatsink this laser good though, it can go at least two minutes before it starts to get warm.

It still trips me out, it is easy for me to trap them while everyone else seems to have difficulties. Although getting one like that is rare, and it was sweet to move it around.

Thanks for checking it out. :yh:

+1 for new things to do with lasers and also tripping me the hell out! Thoughts just raced in my head about the phenomenon that lays 'a foot...

Lol, thanks and don't trip too hard.

It is captivating, and when I made that video I was tripping out. Usually the particles don't last long, but that just hung out. So I started moving the laser... :drool:

okay okay okay that is probably the coolest thing ive seen anyone do with a laser even cooler then all the burning popping and etching and such. Now would that work with a 445nm? at 3w or higher? Or is that a wavelength specific trick? Any more info you can give us on technique?

Wow I had no idea you could do that...
