研究了聚焦连续波(CW)近红外(NIR)激光对L-苯丙氨酸(L-Phe)在其不饱和水溶液表面的激光捕获行为。当照射到溶液表面时,类液体团簇的激光陷阱与局部激光加热同时发生,在焦点处形成无水的板状晶体。随后的激光照射到板状晶体的中心部分,导致激光不仅对L-苯丙氨酸分子/团簇,而且对聚苯乙烯(PS)粒子产生激光俘获。尽管晶体表面不被激光直接照射,但颗粒紧密堆积在晶体的边缘。分子/团簇也被聚集并吸附到晶体表面,导致晶体生长。从晶体内部光传播在晶体表面形成的光势出发,讨论了捕获的动力学和机理。
We present laser trapping behavior of l-phenylalanine (l-Phe) at a surface of its unsaturated aqueous solution by a focused continuous-wave (CW) near-infrared (NIR) laser beam. Upon the irradiation into the solution surface, laser trapping of the liquid-like clusters is induced concurrently with local laser heating, forming an anhydrous plate-like crystal at the focal spot. The following laser irradiation into a central part of the plate-like crystal leads to laser trapping at the crystal surface not only for l-Phe molecules/clusters but also for polystyrene (PS) particles. The particles are closely packed at crystal edges despite that the crystal surface is not illuminated by the laser directly. The molecules/clusters are also gathered and adsorbed to the crystal surface, leading to crystal growth. The trapping dynamics and mechanism are discussed in view of optical potential formed at the crystal surface by light propagation inside the crystal.
