Ran across this little tool not long ago. It's not all encompassing, but it'll generate CDRH-compliant labels based on the power, wavelength and type of laser. Covers most types of lasers including multiline argon, single-line Argon, HeNe, HeCd, Diode, DPSS. Good resolution, makes great labels on a good printer. Might be handy for some of the folks here..
