Solid laser with an emission wavelength of 0.5-0.65 micrometers

摘要

The invention relates to a solid laser with an emission wavelength lying between 0.5 and 0.65 &mgr;m. A chromium-doped Mg.sub.2 SiO.sub.4 (forsterite) laser rod is pumped by a laser diode emitting between 0.75 and 0.8 &mgr;m, this laser diode having an active layer which is Ga.sub.1- x Al.sub.x As based, with x lying between 0.1 and 0.18. The laser device finds particular application in the isotopic separation of uranium.
