Verdet constant measurements of β-barium borate and lead molybdate crystals

Verdet constants of beta-barium borate (β-BaB2O4, BBO) and lead molybdate (PbMoO4, PMO) crystals are measured by comparing with that of terbium-doped glass. Measurement uncertainties caused by light intensity fluctuation, responsiveness drift of photo-detector and unstable amplifying ratio of signal processing circuits can be suppressed by comparative measurement method. Verdet constants of the BBO and PMO crystals respectively are 5.61 ± 0.17 rad.T−1.m−1 and 51.7 ± 1.5 rad.T−1.m−1 for light wavelength of 635nm.
