The objective of this project is to demonstrate polariton lasing from an organic single crystal. To accomplish this a high Q optical microcavity was fabricated via cold welding. The cavity gap was then infused with anthracene and angular emission as a function of ultra-fast optical pump intensity was observed. This resulted in the first observation of room temperature polariton laser emission, including potential BEC of polaritons. This revealed potential for realizing very low threshold, even electrically pumped lasing in organics.
