Fast photodetectors

PD1800 series amplified photodetectors are based on Si or InGaAs ultra-low noise high speed PIN photodiodes. The photodetectors can be used in a wide range of different applications including heterodyne detection of the beat signals between lasers, repetition rate detection of the femtosecond frequency combs, stabilization of the optical fiber length.
