Helium-neon lasers may be little more than glorified ... opposite the Brewster window and aligned to create a resonant optical cavity external to the tube. To switch mirrors easily, [Les] crafted ...

Light enters the cavity through one of the mirrors and bounces back and forth multiple times, creating standing waves at resonant wavelengths. Fabry-Pérot cavities are widely used in lasers, optical ...

This work has been published in Light: Advanced Manufacturing, titled "A quasi-3D fano resonance cavity on optical fiber end-facet for high signal-to-noise ratio dip-and-read surface plasmon sensing." ...

The need to precisely match the laser frequency to cavity resonances can reduce sensitivity, making it difficult to detect ...
