【摘要】：针对现阶段光电对抗单波长激光干扰的局限性,提出了干扰激光双波长复合输出方案,为军用光电对抗设备的通用化和小型化提供了有效思路。利用稳态和速率方程理论分别建立了连续和脉冲激光复合输出模型,通过数值仿真探究了倍频晶体长度和腔镜基频透射率对复合激光输出功率成分的影响。在连续输出状态下,存在最佳基频透射率使基频输出功率最高;对于两种输出状态,都存在最佳倍频晶体长度使倍频输出功率最高。通过实验验证了连续和脉冲输出状态下复合激光输出功率成分随腔镜基频透过率的变化关系,并进一步探究了重复频率对复合激光输出的影响。
[Abstract]:Aiming at the limitation of optoelectronic anti-interference of single wavelength laser at present, a scheme of double wavelength compound output of interference laser is proposed. It provides an effective way of thinking for the generalization and miniaturization of military optoelectronic countermeasure equipment. Using the theory of steady state and rate equation, the continuous and pulsed laser compound output models are established respectively. The influence of the length of double frequency crystal and the transmission rate of mirrors on the output power of composite laser is investigated by numerical simulation. Under the condition of continuous output, the optimal fundamental frequency transmittance makes the output power of fundamental frequency the highest. For two output states. The optimal frequency doubling crystal length makes the output power of frequency doubling the highest. The relationship between the power components of the composite laser output and the transmission rate of the fundamental frequency of the mirror is verified by experiments in the state of continuous and pulse output. The effect of repetition rate on the laser output is further investigated.
