The article currently (2006-02-14) suggests that semiconductor lasers have longer coherence lengths (100 m) than helium-neon lasers (20 cm). I don't think that's generally correct. Perhaps the article should say 100 microns, rather than 100 m. Opinions? ^ I also think these statements are incorrect. Typical coherence lengths of monomode HeNe lasers are 100m to several km, while even a monomode semiconductor laser with a linewidth of about 10pm has a coherence length of about 10cm.
