Beating LIDAR - Achuta Kadambi - MIT Media Lab
Using heterodyning LIDAR to achieve very high resolution at range, and might be able to punch through fog. WHich makes you wonder if the same trick could be used for lasercomm lasers which always had a rain/fog fade problem...

TeraDiode - High Power Diode Laser Technology, Metal Cutting and Laser Welding
Supposedly a rather large improvement on solid state laser diodes. LaserMotive and the beamed power rocket guys will love this, as will the military. Sharks and popcorn sold separately.

These guys are doing a trick analyzing the infrared return wavelengths and running it through a DSP to generate a false color nightvision image that is pretty close to true color.
