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.
