Z-scan confocal method for indirect focus location

We present a new technique that we have defined as the z-scan confocal method to determine the location and size of the focal spot in a tightly focused ultrashort laser pulse. The method permits accurate positioning of a target in the focal spot with a fast response. The technique is designed to hel...
