Abstract

In the past two decades, the important role of high-energy lasers (HEL) has emerged in various civilian and military fields. Therefore, foundations and theories of high-power laser radiation have been developed to serve these applications, including the high-power laser aerosol test chamber. This room simulates different weather conditions in a clear and misty atmosphere. In applications that operate at long range, for example, high-energy laser weapons are used to secure an important area against guided bombs. Changes in climatic conditions are an important and influencing factor in the method of high-energy laser radiation, so atmospheric conditions such as industrial weather had to be simulated in the test room. In this paper the interaction between laser beam and differ-ent metals such as stainless steel and aluminum was measured with accurate values of heat capacity (HC) at 1.4 J\C and melting point (MP) by temperature 600C and 1000C respec-tively reached in the presence of different types of aerosols with real experiments in order to simulate weather conditions in the far field. These experiments were conducted in a High Energy Laser Chamber Test (HELCT) that was previously designed and imple-mented by the authors.
