…compensate low, medium
and high frequencies.The actuators are controlled by
feedback electronics while a high-speed photodiode
simultaneously monitors the laser repetition-rate.
The Synchrolock-AP uses the 9th harmonic content
of the photodiode signal to provide a higher…

…also mean using a photodetector with higher gain and/or lower noise. For example, a particular instrument may only require a zero-gain photodiode or low-cost photodiode array when based on laser excitation, but may need a photomultiplier tube or a CCD array when used with a LED source. For instances…

…Semiconductor Photodiodes
Ideal for low power measurements of CW
lasers, and pulse shape characterization.
Semiconductor photodiodes convert incident photons into charge carriers (electron
and holes), which can be sensed as current or voltage. Photodiodes offer high
