Figure 6From: Laser annealing heals radiation damage in avalanche photodiodes Detection efficiency scan of SLiK-1. (a) Prior to annealing, and (b) after 3.3 W annealing. The spatial profile is essentially unchanged, proving that focused high-power laser illumination does not degrade photosensitivity in the active region of the APD for the power range we tested. The plots at the top are the cross sections at \(Y = 0\).Back to article page
