Using the Novette laser system as a pump, some scientists at Lawrence Livermore
have achieved laser action in thin films of yttrium and selenium.  The yttrium
films emitted coherent X rays at 155 angstroms; the selenium film at 206 and
209 angstroms.  A Princeton scientist has also reported stimulated emission
(although not true lasing) from a carbon target pumped by a CO2 laser, and
expects lasing in a few weeks.
