FIGURE 1. Conventional vs. resonance-free Fabry-Pérot cavity concepts: (a) A conventional cavity with its spectral response and (b) “resonance-free” cavity with its possible spectral response.

What if optical cavities stop resonating?

A novel Fabry-Pérot cavity incorporating a holographic phase mask demonstrates resonance-free operation by driving an unrestricted orbital-angular-momentum ladder-up process, ...
