| Abstract: | The amplification of optical phonons in interface system under the intense laser is first presented. It is well known that the vibration amplitude of the interfacial modes appear damping form. The results show that when the wave vector with parallel to the interface exceeds the damping constant and the field strength exceeds a certain threshold, the population of interfacial optical phonons grows with time. The threshold of field strength and the power of laser required in experiment are approximately estimated. |
