Thermo-Optic Coefficient (∂n/∂T) of 1.3 μm Laser Window Materials

Source

The thermo-optic coefficient (∂n/∂T) of several 1.3 μm laser window materials has been measured in the visible and near infrared spectral regions. These materials include CaF₂, Al₂O₃, MgO, MgF₂, YAG, YLF, water clear ZnS, Kigre Q-98 glass, Corning CORTRAN glasses, and LiF. The measurements were made in the temperature range of 25 to 100 degrees C using a laser interferometric technique. The lasers used were HeNe lasers operating at 0.6328 μm, 1.15 μm, and 3.39 μm and a Nd:YAG laser operating at 1.3 μm.
