Product description
Using a unique patented acousto-optic design, it provides up to 96% single-pass loss modulation, compared to ~85% for conventional designs. Designed for high gain, high power, linearly polarized Nd:YAG and Nd:YVO4 lasers.
Combining optimum grade crystalline quartz, high-quality optical finishing, high-grade anti-reflection coatings, with novel acoustic management and optomechanical design techniques, our q-switches achieve exceptional thermal management while maintaining superior beam quality and high optical throughput.
Key features
- High Damage Threshold
- Improved thermal management
- Superior beam quality
