摘要
根据目前激光武器的发展历程和研制情况,针对其在现代战争中的优势和特点,对激光拒止的光学系统进行设计。激光光源为光纤激光器,激光出射口径3mm,波长1550nm,发散角小于300μrad,采用20倍扩束聚焦光学系统,利用非球面消除光学系统中球差对远场聚焦光斑参数的影响,可实现50m～300m远场聚焦。设计结果满足使用要求,可用于开展激光拒止的研制工作。
According to the development course and development of laser weapon, according to its advantages and characteristics in modern war, the optical system of laser rejection is designed. The laser source is a fiber laser, the laser output aperture is 3 mm,the wavelength is 1550 nm, and the divergence angle is less than 300 μrad. a 20-fold beam expansion focusing optical system is adopted, and the aspheric surface is used to eliminate the influence of spherical aberration on the far-field focusing spot parameters in the optical system. 50 m～300 m far-field focusing can be realized. The design results meet the application requirements and can be used to carry out the development of laser rejection.
