Abstract
We report about the development of novel circuitry for solid state photon counting devices, based on avalanche photodiodes (PC-APD), and tailored for adaptive optics applications. The recent development of EG&G SilkTM devices, has improved silicon. APDs considerably, reducing the afterpulsing effects, improving the effective Q.E., and reducing the dark current to negligible values. These new APD allow to conceive new quenching circuitry and new applications of solid state photon counters for improved adaptive optics performance.
