Webb28 apr. 2024 · Therefore I reduced the case to a simple case by setting the refractive index of the coating as n_coat = 1 (= n_air): a ridge laser emits from its cavity (n = 3.3) to air. In this simple case, one would expect the reflectivity of the laser facet of R = (3.3-1)^2/(3.3+1) ^2 = 0.29. In the attached model, I defined Port 1 as the input port. WebbSolid etalons are simple, flat, very parallel optical components. Sometimes these etalons are used uncoated using only the 4% fresnel refection to provide the etalon effect. Uncoated etalons are often used inside laser cavities since only low finesse is required filter out unwanted laser wavelengths and uncoated etalons are very damage resistant.
