Moving Picture Of Three-Dimensional Image Of Femtosecond Light Pulse Propagating in Three-Dimensional Space

摘要

The authors present a technique for recording and observing three-dimensional image of ultrashoit light pulse propagation as fbim of moving picture. Light-in-flight recording by holography was improved to record the moving picture. A pulse front of collimated femtosecond light pulse propagating in a weakly diffusive medium was observed Also a convergence, divergence, and diffraction of femtosecond laser pulse were observed
