摘要

The generation of circularly polarized light with a high circularity degree and low azimuthal error sensitivity was analyzed using a system composed by two waveplates. It is shown how the high circularity degree is achieved using a combination of a half- (λ/2) and a quarter- (λ/4) waveplate λ/2 + λ/4 configuration. However, the lowest azimuthal sensitivity under small variations in the azimuths of the wave-plates is obtained by employing a λ/4 + λ/2 configuration. Analytical calculus particularized for quartz and MgF_2 waveplates is presented.
