Optical sampling is the technique of reconstructing an electric or electro-magnetic ultrashort signal at a fixed repetition rate by sampling it with a femtosecond laser. Examples are the electron bunches of accelerators, terahertz pulses, microwave pulses, signals in high-speed electronic devices.
When the laser triggers the generation of the signal, the sampling pulses and the signal pulses are automatically synchronized. The sampling results from sweeping the sampling pulses across the signal pulses with the help of an optical delay line. If there is no such triggering, the laser is synchronized to the pulsed signal with the FFS-SYNC-PLL option. Sweeping the delay adjustment of this option enables the sampling. This technique, which is called electrically controlled optical sampling (ECOPS), does not require an optical delay line and is therefore more reliable and faster. One may even use ECOPS when the scientific fiber lasers are required for generating the signal, for example in time-domain terahertz spectroscopy. In this case one uses two FemtoFiber lasers which are synchronized to each other with the FFS-SYNC-PLL option. One laser is used for generating the signal, the other for sampling by means of ECOPS.
