Abstract
AbstractIn 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.
