Abstract
In this presentation, we will present a light source based on adiabatic frequency conversion in millimeter-sized whispering gallery resonators (WGR) made from lithium niobate crystals, that was specifically developed to meet the stringent requirements of a digital holographic measurement system. Further on, first holographic measurements using this light source will be presented. Over 0.4 mW of average output power with 150 ns pulses and a central emission wavelength of 775 nm could be generated by the light source, with a linear tuning behavior of 66 MHz per Volt applied to the WGR.
