Hi, A 4um diameter sphere of calcium carbonate was optically levitated by a laser, and the laser polarization was used to spin the sphere up to 600 million RPM, at which point it disintegrated! http://phys.org/news/2013-08-fastest-rotating-man-made.html I guess it won't be long until someone will do this with diamonds, as they are being optically levitated as well: http://phys.org/n...

310 x 310 x 450 mm volume. I was thinking about doing an unboxing video. Dual independent head. Getting a laser too.

Say I have a laser diode rated for continuous duty at a Vf=4.5V @ 500mA but I want to push it to a higher power but at a lower duty cycle. What's the fancy term for that?

So I get the lonnnng instruction sheet with my toner on how to refill my laser cartridge. :( No no no no.. It's not like that anymore! You go to Youtube and find the video. :) And I found one. And it's so much more clear. Vid beats text. There's no flying cars in this future but the internet is really cool. :)

Hi all, The Chinese are knocking out lasers like these at ridiculously cheap prices currenty: http://tinyurl.com/z59lk8s And I've seen others *even* cheaper than that including postage. There are a good many applications for these parts that spring to mind, but the ones I'm thinking about require some sort of sensor capable of detecting if the beam is broken. I'm not sure what wo...

I got around to testing a whole bunch of laser diodes, which we tune to the 780 nm line of Rubidium. A number of them (~10-20%) have a long wavelength, and I'll have to cool them to T < 10 C*. I'm a bit worried about condensation. (I just have to get below the local dew point.. is that correct?) So I could hold these diodes back, we've got plenty. I then thought that I could run '
