Birefringent tuner for narrowband alexandrite laser

Abstract

This article discusses the possibility of using Lyot interference-polarization tuners to create tunable lasers. The use of various variations and layouts of phase-shifting plates makes it possible to generate both dual-wave and single-wave radiation with the possibility of tuning. The tuning range depends both on the specific type of tuner used and on the parameters of the cavity and active medium. Dual-wave and single-wavelength generation of an alexandrite laser is demonstrated.
