The optical magnetic sensor using Nd doped YAG crystals

The optical magnetic sensor using Nd doped YAG crystals

The magnetic field dependence of photo luminescence (PL) peak split and peak intensity rate from Nd doped YAG crystal was studied for the optical-magnetic sensor application. Photoluminescence peaking at the wavelength from 800 nm to 1400 nm are observed in Nd doped YAG crystal at room temperature....

Beschreibung
Zusammenfassung:The magnetic field dependence of photo luminescence (PL) peak split and peak intensity rate from Nd doped YAG crystal was studied for the optical-magnetic sensor application. Photoluminescence peaking at the wavelength from 800 nm to 1400 nm are observed in Nd doped YAG crystal at room temperature. The feature of these PL peaks split with magnetic field. Peak intensity rate and Peak split of PL from Nd doped YAG crystal linearly with the magnetic field increasing from 0.0 T to 8.0 T at room temperature. Fluorescence optical magnetic sensor system using fluorescence sensor crystal enables non-contact magnetic field measurements.
