The Verdet constant of Er-doped crystalline YAG and tellurite glass at 1645 nm
We describe the measurement of the Verdet constant of undoped and Er-doped crystalline YAG and tellurite glass at 1645 nm. The undoped YAG value is compared to those measured using visible light. We show that the paramagnetic nature of Er reduces the Verdet constant but that the decrease is probably not significant for the typical Er doping levels used in Er:YAG or in Er:tellurite-glass mid-IR lasers.
