Paper Abstract

As a part of a project for using short laser pulses and holographic techniques to measure three-dimensional shapes, measurements have been carried out of the pulse shapes of laser pulses from a mode-locked argon-ion pumped dye laser with autocorrelator, light-in-flight recording by holography and nonscanning white-light interferometer. The aim of the study is to find a reliable, inexpensive and fast method for measuring the pulse length of laser pulses in the picosecond region, when exposing and reconstructing the light-in-flight hologram, in respect to pulse width, symmetry and signal-to- noise ratio. Experimental results, along with the theoretical background, from these tests are accounted for in this presentation.
