Shaped mirrors in plano-concave cavities increase central emitter coupling by up to an order of magnitude in simulations, matching concave-concave performance with better alignment tolerance.
An analytical model predicts that thermoelastic mirror deformation from light absorption caps focal intensity at 2.9 TW/cm² in low-absorption Fabry-Pérot cavities, with experiments reaching 70% of this limit.
