Construction of helium neon laser
WebMar 18, 2024 · This gas laser is a four-level laser that use helium atoms to excite neon atoms. It is the atomic transitions in the neon that produces the laser light. The most … WebIn sealed lasers, this takes place as the helium atoms strike the walls of the laser discharge tube. In flow-through lasers, a continuous stream of CO 2 and nitrogen is excited by the plasma discharge and the hot gas mixture is exhausted from the resonator by pumps. The addition of helium also plays a role in the initial vibrational excitation of N

WebAs shown in the Lasers Specification Guide, all lasers consist of three components: an energy source (also known as a pump), a laser (or gain) medium, and an optical resonator; these components are shown in the image below. Essentially, the pump provides energy which is amplified by the gain medium.
