Nonlinear pulse compression by optical frequency mixing in crystals with second-order nonlinearity
A Dubietis, G Valiulis, R Danielius and A Piskarskas
Show affiliationsA novel and promising light pulse compression technique based on frequency conversion in nonlinear crystals is reviewed and discussed in some detail. Five- to sevenfold compression of light pulses of different wavelengths and initial pulse widths providing an intensity conversion rate as high as 400% is demonstrated. It is shown that adaptively tilted pulses ensure modification of group velocity mismatch of interacting pulses in a 
medium and significantly extend the list of suitable crystals as well as the pulse compression rate. The results of 1.3 ps tilted pulse compression up to 150 fs due to second- and third-harmonic generation in BBO II and KDP I crystals, respectively, are presented.
