The role of amplified spontaneous emission in cryogenic optical refrigeration

27 January 2022 • 8:55 AM - 9:20 AM PST | Room 308 (Level 3 South)


The effects of amplified spontaneous emission (ASE) as well as absorption saturation in cryogenic optical refrigeration in rare-earth doped materials are analyzed theoretically. It is seen that ASE may pose a limitation on power scaling under strong feedback conditions (i.e. in high finesse pump circulator cavities). Absorption saturation may have similar effect depending on the value of the background absorption.
