Design of true zero-order half-wave plates using KCsMoP2O9 crystal: A novel molybdophosphate material with extremely small birefringence
Source abstract
Abstract
The true zero-order half-wave plates (HWPs) with millimeter thicknesses were manufactured using the KCsMoP 2 O 9 (KCMP) crystal with extremely small birefringence (Δn = 0.007 at 1064 nm). The designed KCMP HWPs showed small sensibility (wavelength, temperature, and angle), wide operating waveband (50 nm at >200:1), good thermal stability (>900:1 at 80 o C), high extinction ratio (>2500:1), and excellent phase-retardation characteristics. In addition, an optical attenuator assembly of KCMP HWP (A16M0) and polarizers was designed. The transmittance could be adjusted well from 0 to 1 by the designed optical attenuator, comparable to commercial quartz HWP (glued zero-order HWP). All results indicated that the KCMP crystal is a good candidate as a wave plate material with the potential for polarization modulation in optical systems.
