We present the generation of amplitude-, phase-, and polarization-controlled femtosecond laser pulses tunable in the ultraviolet (UV) between 305 nm and 370 nm by nonlinear optical methods. Two delayed sets of individually amplitude- and phase-shaped pulse profiles in the visible are transferred into the UV via two independent sum-frequency generation (SFG) processes in two perpendicular oriented nonlinear crystals. The two resulting shaped UV light fields of orthogonal polarizations are temporally recombined via a birefringent material. Common-path geometry throughout the entire setup is ensured for interferometric phase stability. Examples for polarization pulse shaping around 360 nm are demonstrated with emphasis on the creation of interferometrically stable polarization-controlled optical pulse trains.
