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.
在空气中，从正交晶体制备的 5,5'-双(4'-甲氧基联苯-4-基)-2,2'-联噻吩 (BP2T-OMe) 晶体中稳定地观察到室温激光。单晶的一对平行 {110} 面充当有效的法布里-珀罗反射镜。这种显著的激光基于正交晶体谐振器的高群折射率（3.5）和 Q 因子（4500），表明 BP2T-OMe 有望成为有机激光介质。
