Material Detail

As a consequence of the time-bandwidth uncertainty principle, ultra short laser pulses carry significant bandwidth. If the spectral components that fall under the bandwidth of the laser pulse are time coincident, the pulse is said to be at its transform limit. A transform-limited pulse implies that the pulse duration is minimized. Material properties, such as dispersion, alter the (phase) relationship between the spectral components of light, effectively separating the blue and red components of the pulse in time." This report focuses on the use of frequency-resolved optical gating (FROG) to measure short pulse LASER Chirp.
