Pulse Measurement tools provide measurement of a laser pulse, allowing the monitoring of the pulse shape.
Phase Measurement
Phase measurement tools use the spectral phase profile to measure the input pulse.
Autocorrelation
Interferometric autocorrelators are the most common tool used for the measurement of optical pulse width in the femtosecond and picosecond time regime. Autocorrelators specifically designed for measuring the output pulses of Ti:sapphire femtosecond laser oscillators and amplifiers are available. |
