General Description
Acousto-Optic Q-Switches (AOQS) are advanced devices designed for efficient Q-switching in laser cavities. By increasing diffraction loss during pumping, AOQS devices ensure the laser cavity remains in a low Q-value state. This allows a large accumulation of inverted particles in the upper energy level. When the diffraction loss is rapidly removed, the cavity transitions to a high Q-value state, enabling the release of high-energy pulses in the form of giant laser bursts. POC’s AOQS devices are tailored for use in applications requiring high peak power, pulse stability, and rapid switching. Constructed using premium materials such as fused silica and crystalline quartz, these switches guarantee excellent transmittance, low insertion loss, and high damage thresholds, making them ideal for demanding industrial and scientific applications. To achieve optimal performance, higher RF power injection and efficient heat dissipation are essential for larger aperture devices. Water cooling options are available to ensure stable operation under high-power conditions, further enhancing device longevity and reliability.General Applications and Examples
- Laser Marking and Engraving: AOQS devices enable precise pulse control for creating detailed engravings and markings on various materials, including metals, plastics, and ceramics, ensuring high-quality results.
- Medical Laser Systems: Used in therapeutic and surgical applications, AOQS devices provide stable, high-energy laser pulses for procedures like tissue ablation and photocoagulation, ensuring precision and safety.
- Material Processing: AOQS devices enhance laser-based material processing, such as micromachining, cutting, and welding, by delivering controlled high-power laser pulses for superior processing efficiency.
