I will discuss radio observations of molecular gas in two populations of starforming galaxies at high redshift (selected based on their rest-frame ultraviolet and far-infrared emission) and what we can learn from them.

Lasers in semiconductors, atomic gas, optical fibers and infrared and ultraviolet molecular gas are treated as well as non-linear frequency conversion, short-wavelength lasers and the seeming paradox of ultrafast lasers.
