Photophoresis denotes the phenomenon that small particles suspended in gas (aerosols) or liquids (hydrocolloids) start to migrate when illuminated by a sufficiently intense beam of light. The existence of this phenomenon is owed to a non-uniform distribution of temperature of an illuminated particle in a fluid medium. Separately from photophoresis, in a fluid mixture of different kinds of particles, the migration of some kinds of particles may be due to differences in their absorptions of thermal radiation and other thermal effects collectively known as thermophoresis. In laser photophoresis,
光泳（英語：Photophoresis）是指懸浮在氣體（氣溶膠）或液體（氣溶膠）中的小粒子，當被足夠強度的光照射時，會開始往遠離光源的方式移動的現象。光泳的原因是因為在流體中的小粒子，受光照射後出現不均勻溫度分佈所造成。
