Preliminary results in the development of a multi-colour pulsed laser for holography

Abstract

This paper presents the development of a pulsed, high coherence multi-wavelength laser for colour holography. The laser operates in five different wavelengths to provide a very good coverage of the chromatic range. All the wavelengths are simultaneously derived from a single Nd:YAG laser source through Raman wavelength shifting and harmonic conversion processes, making the system fairly compact and robust.
