Method and device for measuring length of pulse in very short light pulses like femto and pico-second laser pulses detects partial rays of equal optical properties and without time delay separately regarding pulse characteristics.
Method and device for measuring length of pulse in very short light pulses like femto and pico-second laser pulses detects partial rays of equal optical properties and without time delay separately regarding pulse characteristics.
Partial rays (3,4) of equal optical properties and without time delay are separately detected regarding pulse characteristics that depend differently on the pulse length of light pulses (1) to be analyzed. Detector signals (7,8) from the partial rays are evaluated in relation to one another directly or, if necessary, after amplification (9,10).
