Abstract
Conference Title: 2014 Conference on Lasers and Electro-Optics (CLEO) Conference Start Date: 2014, June 8 Conference End Date: 2014, June 13 Conference Location: San Jose, CA, USA We measure atomic polarization relaxation-time of Rb-loaded in different hypocycloidal-core Kagome HC-PCFs. The measured relaxation-time is two-orders of magnitude larger than the transit-time limit. We attribute this to slow-atom stronger contribution to the polarization build-up.
