摘要
激光武器具有速度快、精度高、拦截距离远、火力转移迅速、不受外界电磁波干扰、持续战斗力强等优点,成为防御快速、小型、高机动平台及武器如无人机、高精度制导导弹、炮弹及炸药等的有效手段。为了提升激光武器的杀伤效能,需要高功率、大能量的激光器,传统的激光器功率提升受限于工作物质的热效应,而光学级的金刚石拥有极高的热导率、极宽的光谱透过范围、极高的物理和化学稳定性,同时具有优异的拉曼和布里渊非线性特性,在提升激光功率能力上具有突出的表现,有望用于研制新一代的强功率激光武器。文章介绍了拉曼金刚石激光器和布里渊金刚石激光器的原理、发展现状及趋势,最后对应用场景进行了展望。
Laser weapons have the advantages of high speed,high precision,long interception distance,rapid fire transfer,no interference from external electromagnetic waves,strong sustained combat effectiveness,etc.Therefore,laser weapons have become an effective means to defend fast,small and highly mobile platforms or weapons,such as UAVs,high-precision guided missiles,shells and explosives.In order to improve the killing efficiency of laser weapons,high-energy lasers are needed.However,the power enhancement of traditional lasers is limited by the thermal effect of their working materials.It is found that optical grade diamond has high thermal conductivity,wide spectral transmittance,high physical and chemical stability,and excellent nonlinear properties such as Raman effect and Brillouin effect.It has outstanding performance in improving the output capacity of laser,and is expected to be used in a new generation of high-power laser weapons.This paper introduces the principle,development status and trend of Raman diamond laser and Brillouin diamond laser,and finally prospects their application prospects.
