Development and characterization of high suppression and high etendue narrowband spectral filters.
The present work addresses critical issues in constructing high suppression, narrowband spectral filters in rare earth ion doped crystals, mainly targeting the application of ultrasound optical tomography but is also applicable for areas such as quantum memories, self filtering of laser frequencies, and other applications relying on high absorption in rare earth ion doped crystals. The polarization of light transmitted through a highly absorbing crystal is experimentally analyzed. Additionally, an existing wave propagation method is used to simulate beam propagation through a spectral hole to study the high etendue requirements of ultrasound optical tomography.
