Hug a Laser

It is my duty as a blogger to mention lasers in this time of international laser celebration. This May is the 50th anniversary of the first lasers. Everyone knows a laser that they love, right? We all use them. So, instead of talking about lasers, I am going to post some great links to other laser stuff (including some of my stuff).

the history of the first lasers (AIP)


The above is the American Institute of Physics's presentation of the history of the laser. Really, this does a great job of giving all the details you would want. I highly recommend it.

Uncertain Principle's Laser applications

Chad gives the result of his laser smack down poll for most amazing applications of lasers (voter based). I guess I can tell you that the winner of voting is Laser cooling.

Laser Recoil discussion

The Virtuosi and Built on Facts have some nice posts about lasers and recoil (for laser guns).

Some of my stuff

Honestly, I have not done that much stuff with lasers. Really most of my laser stuff just uses lasers for something else.

Fluorescence with a green laser pointer

Ruff Ruffman tries to measure temperature with a laser

Lizards like green laser pointers too.

I am sorry to point this out, but I can't help it. My kids watch this show "Fetch with Ruff Ruffman". It's mostly an ok kids show. However, there was a problem. In one episode, some kids were in the desert and measuring temperature with (they said it several times and it was even a quiz…
The Virtuosi: Would a laser gun recoil? "Let's motivate our question a little bit. I've wondered about this question since I saw star wars. Though I'm no firearms expert, the recoil in guns must come from conservation of momentum principles. Momentum is conserved in a system. The gun starts with…
There's a really snazzy physics blog run out of Cornell called The Virtuosi. Sort of like this blog, they're big fans of looking at interesting scenarios through the equations of physics. Not long ago, they had an interesting post looking at whether or not laser guns would have recoil. I'm not…
Do you have a green laser pointer? You should. They are relatively inexpensive now. What if you take your laser pointer and aim it at stuff in your house? The laser dot always looks green, right? This is actually a pretty important point about color. Suppose I have the lights on in a room and…

I definitely have lasers I want to hug, but more often than not, I have lasers I want to kick. It's too bad these lasers cost more money than I'm likely to make in my lifetime otherwise I would kick 'em! Stupid lasers.

The AIP exhibit certainly looks interesting, but the link gives me a 404...
