Abstract

In this paper, continuous-wave and cavity-dumped Nd:YVO4 lasers are studied. Firstly, through theoretical analysis and numerical simulation, the output characteristics of a continuous-wave laser based on the magneto-optical effect are analysed using the rate equation. The continuous adjustment of output power and pump threshold power is realised using the magneto-optical effect to rotate the polarisation direction of laser. The theoretical simulation results show that the output power of the laser could be effectively controlled under different magnetic field intensities. On this basis, the authors explore the cavity-dumped laser system based on the magneto-optical effect. By adjusting the intensity of the magnetic field and rising edge time, the pulse width and waveform could be flexibly adjusted. The relationship between the magnetic field intensity in the low Q period and the spot radius of the pump and the signal beam and the output energy and the output pulse waveform is analysed. These research results lay a foundation for further optimising the design and application of magneto-optical effect lasers.

基于磁光效应的连续波腔倾倒1064 nm Nd:YVO4激光器

本文研究了连续波和空腔倾倒Nd:YVO4激光器。首先，通过理论分析和数值模拟，利用速率方程分析了基于磁光效应的连续波激光器的输出特性。利用磁光效应旋转激光器的偏振方向，实现输出功率和泵浦阈值功率的连续调节。理论仿真结果表明，在不同磁场强度下，激光器的输出功率可以得到有效控制。在此基础上，作者探索了基于磁光效应的空腔倾倒激光系统。通过调节磁场强度和上升沿时间，可以灵活调节脉冲宽度和波形。分析了低Q周期磁场强度与泵浦光斑半径、信号束、输出能量和输出脉冲波形之间的关系。这些研究结果为进一步优化磁光效应激光器的设计和应用奠定了基础。
