HeCdlaserit
HeCdlaserit, also known as the Helium-Cadmium laser, is a gas laser that emits light in the blue and ultraviolet regions of the electromagnetic spectrum. It operates by exciting a mixture of helium and cadmium vapor. The primary laser lines are at 441.6 nm (blue) and 325.0 nm (ultraviolet). These wavelengths make it useful for a variety of scientific and industrial applications.
The construction of a HeCd laser typically involves a sealed tube containing helium gas and a small
HeCd lasers are known for their relatively high power output in the blue and UV ranges compared
