Abstract

The geometrical scaling for radio frequency excited slab waveguide molecular lasers has been described in recent years by the concept of similarity and similarity scaling laws^[1]. This provides a method to relate pressure p, electrode spacing d and excitation frequency f such that we can understand and predict the behaviour of the slab waveguide laser. In practice the lack of power supplies with an adequate range of frequency tunability make it difficult to fulfil the similarity conditions. A necessity has arisen for a more realistic model which describes laser behaviour over a wide electrode separation range where the excitation frequency remains constant.
