Abstract
Sub-20fs, wavelength tunable, uJ-level DUV pulses were generated by using nondegenerate, chirped-pulse four-wave mixing in CaF2 crystal. The DUV spectrum can be tuned from 257nm to 277nm with widest spectral width of 16.8nm. The compact DUV laser system is useful in pump-probe experiment for investigating ultrafast dynamics in biological molecules.
