Optical manipulation of a lasing microparticle in water was demonstrated. A rhodamine B-doped poly(methyl methacrylate) particle was simultaneously manipulated and pumped by 1064 nm CW and 532 nm pulsed Nd3+:YAG laser beams, respectively. Optical interactions between lasing and closely positioned nonlasing particles were studied by a multibeam laser micromanipulation technique.
