This invention discloses an acousto-optic Q-switching method for carbon dioxide lasers, specifically relating to the field of acousto-optic Q-switching of lasers. It addresses the problem that existing Q-switching control methods rely on fixed delays or single feedback, making it difficult to adapt to changes in discharge state, resulting in large pulse energy fluctuations and poor stability. By acquiring and segmenting the voltage and current waveforms within each discharge cycle, multi-dimensional features of the pre-ionization, main discharge, and relaxation stages are extracted to construct a full-cycle state vector. Based on this state vector, a timing prediction network is used to output the Q-switching turn-on delay and acousto-optic diffraction efficiency setpoints for the next cycle, achieving dynamic prediction and adaptive adjustment of Q-switching parameters. This improves the stability and consistency of laser pulse output, enhances peak power control accuracy and adaptability under different operating conditions, while reducing the reliance on manual experience for parameter tuning and improving the long-term reliability and robustness of the system.

The sliding block, limited by the sliding rod, adjusts the end cap spacing. This structural design achieves precise control of the end cap spacing through the synergistic effect of mechanical transmission and the limiting mechanism.
