Dielectric mirrors coating of the active medium for diode pumped Erbium laser
Additional Document Info
The paper presents the design and realization of the cavity mirrors for a 2.94 m Er laser, longitudinally pumped by a diode laser emitting in 0.97 m range, used in stomatology applications. The total reflection mirror is a dichroic one with the third harmonic in reflectance spectral characteristic suppressed. The study on the harmonics suppression that we present was based on the theory of the finite thickness inhomogeneous layers and the results were used in the mirrors design. The theoretical and experimental reflectance spectral dependencies are presented.
