Summary
We analyzed a four-mirror-cavity enhanced Michelson interferometer for improved sensitivity. This design minimizes thermal lensing and contrast loss, enabling high circulating powers in transmissive optics.
Area of Science:
- Optics and Photonics
- Interferometry
- Laser Physics
Background:
- High circulating powers in interferometers can cause thermal lensing and reduce contrast.
- Transmissive optics are often preferred but susceptible to these issues.
Purpose of the Study:
- To investigate the shot-noise-limited sensitivity of a novel four-mirror-cavity enhanced Michelson interferometer.
- To mitigate thermal lensing and contrast reduction in high-power optical systems.
Main Methods:
- Derivation of analytical expressions for light fields and frequency response.
- Detailed analysis of resonance features within the interferometer's parameter space.
Main Results:
- Established boundary conditions for systematic parameter studies in an 11-dimensional parameter space.
- Demonstrated a method for analyzing complex interferometer configurations.
Conclusions:
- The four-mirror-cavity design offers a viable approach to enhance interferometer sensitivity.
- This topology effectively addresses challenges associated with high circulating powers and transmissive optics.
