Abstract

With a focused laser beam, we make a microscopic change on a thin film, and organize the overall system that can observe the change with a microscope. This system utilizes the energy of a laser beam which is focused by a simple lense system. That is a laser beam which has its waist at working distance of a lense. The microscopic change induced by the energy of laser beam focused through a lense can be observed in real time. The experiment with this system shows that the 10mW He-Ne 632.8nm laser can change the black vinyl instantaneously.
