Abstract : An ultraviolet beam (337.1 nanometers) from a pulsed nitrogen gas laser fired through a fluid containing a photochromic dye produces opaque traces in the fluid along the path of the laser beam. Subsequent movement of the fluid deforms the opaque traces and produces a record of the fluid flow. A high powered laser has been designed, built, and tested. Velocity distribution have been obtained in slowly forming droplets of solvent in an immiscible ambient fluid. (Author)
