One of the first of all lasers was the well known Helium Neon Laser. Its excellent beam quality and coherence made it to one of the mostly used in many laser applications. This educational kit has been designed to supply the students in understanding the interaction of the different components of a gas laser up to the influence of different optical components used with gas lasers.

An open frame gas laser consisting of a HeNe tube with bewster windows and separate resonator mirrors shows the relations very impressive. The basics of gas lasers like stability, coherence and mode behaviour are shown in pactice and discussed in the comprehensive manual. The possibilities of wavelength selection with optical components like Littrow Prism and birefringent filter is investigated and described.

The influence to the laser resonator modes with the help of an etalon inside the laser cavity is imparted to the students. All optical and mechanical parts for setting up the kit are included.

A quick start-up alignment of the laser resonater is ensured by delivery of an adjustment HeNe laser in holders to define the optical axis on the main rail.
