- **Caution**: 

### Q: What is the primary function of an output coupler mirror in optical systems?
**A**: An output coupler mirror is designed to allow a controlled fraction of light to exit an optical resonator while reflecting the remainder back into the cavity to maintain resonance, enabling useful output from lasers or other optical devices.

### Q: How do materials like fused silica and Zerodur benefit output coupler performance?
**A**: Fused silica offers low thermal expansion and high laser damage thresholds, while Zerodur provides near-zero thermal expansion for stability in precision applications. Both materials ensure minimal distortion and reliable performance in varying environmental conditions.

### Q: What specifications should I consider when selecting an output coupler mirror?
**A**: Key specs include reflectivity/transmission ratio, substrate material (e.g., fused silica, Zerodur, BK7), coating type (dielectric), surface quality, wavefront distortion, and mounting interface compatibility to ensure integration with your optical resonator setup.
