Abstract

Room temperature lasing was stably observed in air from an orthorhombic crystal of 5,5'-bis(4'-methoxybiphenyl-4-yl)-2,2'-bithiophene (BP2T-OMe). A pair of parallel {110} facets of the single crystal acted as effective Fabry-Pérot mirrors. This prominent lasing is based on high group refractive index (3.5) and Q factor (4500) of the orthorhombic crystal resonator indicating a promising potential of BP2T-OMe for organic laser media.
