Source: MDPI Numerical Representation of Ultrashort Pulses Introduction In the field of optics, numerical simulations of pulse propagation require a method to represent pulses numerically. The representation differs based on the pulse duration – longer pulses can be represented by optical power versus time, while ultrashort pulses with picosecond or femtosecond durations require a time-dependent […]

Source: Femto Easy Understanding Optical Autocorrelators Introduction Optical autocorrelators are essential tools used for analyzing light, particularly for measuring the duration of ultrashort pulses in the picosecond or femtosecond range. These devices operate based on the principle of checking the correlation of the temporal pulse trace with itself. Autocorrelators come in different types, such as
