Laser Microscope

"After witnessing the image of a mosquito in a laser beam outside, I decided to investigate the phenomenon further. I started by locating scuzzy water. Ponds lacking, I decided to take water out of the bowl of my 6 year old spider plant. I then filled a syringe and hung it above a laser so that a drop of water, almost ready to fall, was in the beam path." [via]

I'll take lasers for $800, Alex

Sam's Laser FAQ is an online bible for laser enthusiasts (of all shapes, sizes, colors, and creeds). Curious novices can start by learning how lasers work and what is inside those nifty green laser pointers. Graduate students, why not fix up that large frame Argon-ion laser sitting the back of the lab? Or just build your own? Of course there are lots of pretty pictures and for hobbyists not terribly interested in glorious amounts of light, don't miss the wonderful discrete semiconductor test guide thrown in for free. And above all, MeFi, let's think safety.
