Abstract
Directed energy weapon (DEW) is the weapon equipment directly attacking targets through high-energy beams, wherein the fiber laser consumes energy and generates a lot of waste heat in the process of generating laser. The heat must be rejected in time, otherwise the efficiency of the fiber laser will be greatly compromised. Therefore, this paper analyzes the thermal characteristics of the fiber laser. A model of the fiber laser is established based on the laser composition principle. Simulations are carried out under different working conditions and show that fiber laser efficiency is mainly related to junction temperature. A thermal management system is designed. The volume, weight and temperature of cold tank are evaluated and provided as references for the thermal management system design of directed energy weapons.
