用紫外激光光解吸附的有机金属分子生长金属薄膜，观察到亚微米空间周期的涟漪形貌。这种结构的发展从表面粗糙度通过耦合的入射UV场的表面等离子体波。由于入射激光场和表面等离子体波之间的干涉的强度变化调制膜的生长速率，这反过来又增强了入射场的散射成表面等离子体波;指数增长的不稳定性的结果。
Ripple morphologies of submicrometer spatial period are observed on metal films grown by UV laser photolysis of adsorbed organometallic molecules. This structure develops from surface roughness by coupling of the incident UV field to a surface-plasma wave. The intensity variation due to interference between the incident laser field and the surface-plasma wave modulates the film growth rate which in turn enhances the scattering of the incident field into the surface-plasma wave; an exponentially growing instability results.
