Paper Abstract

We propose a technique to record and observe a propagating ultrashort laser pulse as a form of motion picture of three-dimensional image. The technique is based on the light-in-flight recording by holography and it uses a weakly light-scattering three-dimensional medium to generate the three-dimensional image of the propagating laser pulse. In the reconstruction, we gaze the hologram illuminated with a continuous wave laser and move along the hologram, then the motion pictures can be seen. The motion pictures are continuous in terms of both time and space. The reconstruction speed of the motion pictures is determined by the speed of the moving. We constructed the light-scattering medium using gelatin jelly and conducted the experiment of the recording and reconstruction of the motion pictures of the ultrashort laser pulses propagating in three-dimensional space and conducted the experiment to record and to observe the motion picture. The motion pictures of the femtosecond laser pulse propagating in the gelatin jerry were observed as a form of three-dimensional images. We discuss the characteristics of the motion pictures acquired by the proposed technique.
