Abstract
Ultrashort laser pulses are widely used to investigate extremely fast processes in many fields of science. Other applications, such as digital holography [1], can benefit from the broadband spectra of these pulses. For measuring the shape of rapidly moving objects, digital holography requires a bright source with clearly separated spectral components. Here we demonstrate a novel scheme for a coherent multicolor femtosecond source, based on an adapted commercial Ti:sapphire amplifier system, and demonstrate its performance by simultaneously recording of two digital holograms using ultrashort pulses.
