helium-cadmium laser

helium-cadmium laser

[′hē·lē·əm ′kad·mē·əm ′lā·zər]
(optics)
A metal-vapor ion laser in which cadmium vapor, produced by heat or other means, migrates through a high-voltage glow discharge in helium, generating a continuous laser beam at wavelengths in the ultraviolet and blue parts of the spectrum (about 0.3 to 0.5 micrometer).
