Saw some supercontinuum (a better explanation here) generation in the lab today. At the top there's a diode laser at 808 nm (the bright white light in the pic, try photographing your TV-remote with a digicam!) that pumps a YAG laser which outputs a 1064 nm pulse. This is then converted to a 532 nm pulse through second harmonic generation and directed into a very fancy holey-fiber in which the supercontinuum is created. In the middle of the pic there are two reflections from a diffraction grating. To the right the zero order diffraction which looks like mostly 532nm to the camera/eye, and to the left the 1st order diffraction where you see a fair bit of blue to the right of the 532nm peak and a bit of yellow/red(ish) to the left of the peak.
