we could expand visible radiation a little... Maybe a listing of common lasing wavelengths?

A few off the top of my head...
3u-1.5u Er (YAG. Glass)
1.5u - CO2
1.6u - Nd (YAG/YV04/YLF)
980nm - used for pumping Er
800nm- used for pumping Nd
780nm- CD read laser
700nm - Ruby
650nm - DVD read laser
640nm - HeNe
500-300nm- Argon
530nm - 200nm harmonics of Nd
400nm - Blu-Ray/HD-DVD read laser

heck, if you really wanted to get deep you could list the bands for telecommunication (C at like 1550, L at 1400ish, etc)

Wow, nice work Chris.

160-190 kHz experimental radio band

The UVC band 200 nm - 31 nm are used a lot for serialization.

Thanks for the input. I've always seen charts like this, but lacking some of the details. Some only list wavelengths, some only list frequencies, etc. I was thinking of breaking down visible light at least into colors. Lasing wavelengths sounds like a good idea as well.

The lowfer bands sound good as well. The US allocation is 160-190khz, and the UK has 135.7-137.8khz, IIRC.
