Abstract

The helium cadmium (HeCd) laser is a gas laser in which the active species is ionized cadmium metal vapor in helium buffer gas. It is similar in some respects to the HeNe laser. Continuous wave emission occurs in the deep blue at 441.6nm and in the near uv at 325nm. Short wavelength output of high spectral purity and excellent mode quality makes the HeCd laser uniquely useful in many applications.
