A Guide to Pumping a Helium-Neon Laser using Electric Discharge

The Wavelength Requirement for Pumping a Helium-Neon Laser

In order to pump a helium-neon laser using electric discharge, the appropriate wavelength of electromagnetic radiation would depend on the specific energy levels of the helium and neon atoms involved in the laser system.

In the case of a typical helium-neon laser, the pump wavelength required is in the ultraviolet (UV) range. The UV radiation is used to excite the helium atoms to higher energy levels, which then transfer their energy to the neon atoms. This energy transfer stimulates the emission of coherent light at the desired wavelength, typically in the red or infrared range.

The specific wavelength needed for pumping a helium-neon laser would depend on the design and configuration of the laser system. Typically, UV radiation with a wavelength in the range of 240-280 nm is used for this purpose. However, it's important to note that the exact wavelength requirements can vary depending on the specific laser setup and the desired operating conditions.

It's worth mentioning that pumping a helium-neon laser using electric discharge is a complex process that requires precise control and specialized equipment. Therefore, it is typically performed in controlled laboratory settings by experts in laser technology.
