Non-resonant adiabatic photon trap
The paper presents and experimentally investigates a concept of an efficient radiation trap based on adiabatic photon confinement between curved mirrors. Such a trap is free of restrictions typical to the Fabry-Perot cells, relating to the confined radiation quality and accuracy and stabilization of optical elements. Experiments have demonstrated high efficiency of confinement, which depends mainly on the reflectivity of the mirrors and defects on their surface.
