Non-uniform Birefringence in Highly-reflective Substrate-Transferred GaAs/AlGaAs Coatings at 1064 nm
Andri M. Gretarsson, Ambroise L. M. Juston, Benjamin Nicolai +8
Using a custom-built scanning system, we generated maps of birefringence on reflection at ~nm from single-crystal GaAs/AlGaAs Bragg reflectors (hencefort…
