Technical Review for Lasers Used in Optical Countermeasure

Abstract

The development of laser technology is very fast in recent years.A variety of laser sources have been regarded as the key component in many optoelectronic devices.For directed energy weapon,the progress of laser technology has greatly improved the tactical effectiveness,such as increasing the range and strike precision.At the same time,the modern solid-state laser has become the ideal optical source for optical countermeasure,because it has high photoelectric conversion efficiency and small volume or weight.However,the total performance is limited by the mutual cooperation between different subsystems.The optical countermeasure is a complex technique after many years development.The key factor to evaluate the laser weapon can be formulated as laser energy density to target.The technical review for laser used in optical countermeasure is briefly introduced in this paper.Especially the essential techniques are discussed for the laser used in the optical countermeasure system,so that the laser has a better compatibility to total system.In this way,the maximum energy emitted by the laser source can be utilized.
