Fiber pigtailed pulse pickers

A pulse picker is an electrically controlled optical switch used to extract single

pulses from a fast pulse train.

Short and Ultrashort pulses are in most cases generated by a mode-locked laser

in the form of a pulse train with a pulse repetition rate of the order of 10 MHz –

few GHz.

For various reasons, it is often necessary to pick certain pulses from such a pulse

train, i.e., to transmit only certain pulses and block all the others. This can be done

with a pulse picker, which is essentially an electrically controlled optical gate
