利用1064 nm连续激光单束聚焦，在水中实现了对罗丹明640掺杂聚苯乙烯乳胶粒子的同时光学操纵和激光作用。从发射光谱中周期性间隔的峰以及发射强度与入射激光功率的非线性(多于二次)关系证实了由双光子吸收引起的粒子的激光。
Simultaneous optical manipulation and lasing of a rhodamine 640-doped polystyrene latex particle in water was demonstrated through irradiation of a single focused 1064 nm CW Nd:YAG laser beam. Lasing of the particle resulting from two-photon absorption was confirmed from periodically spaced peaks in the emission spectrum and from nonlinear (more than quadratic) dependence of the emission intensity upon the incident laser power.
