We demonstrate the generation of 100-μJ-level multicolored femtosecond pulses based on a single-stage cascaded four-wave mixing (CFWM) process in a thin glass plate by using cylinder lenses. The generated high-energy CFWM signals can shift the central wavelength and have well-enhanced temporal contrast because of the third-order nonlinear process. They are innovatively used as clean sampling pulses of a cross-correlator for single-shot temporal contrast measurement. With a simple homemade setup…

Temporal contrast reduction techniques for high dynamic-range single-shot temporal contrast measurement

A single-shot characterization of the temporal contrast of a petawatt laser pulse with a high dynamic-range, is important not only for improving conditions of the petawatt laser facility itself, but

Temporal contrast reduction techniques for high dynamic-range temporal contrast measurement.

The proof-of-principle experiments applying single stage of pulse stretching, anti-saturated absorption, or optical Kerr effect successfully reduce the temporal contrast by approximately one order of magnitude and it is expected that a higher dynamic-range temporal contrast can be characterized by using cascaded temporal contrast reduction processes.

These novel MUCAU-VB, which are manipulated in temporal, spectral, spatial domain and polarization state simultaneously, are expected to apply in wide fields, such as manipulating particles and multicolor pump-probe experiments.

Single-shot measurement of >1010 pulse contrast for ultra-high peak-power lasers

By integrating both the techniques of scattering-noise reduction and sensitive parallel detection into SSCC, this work demonstrates a high dynamic range of >1010, which, to the best knowledge, is the first demonstration of an SSCC with a dynamic range comparable to that of commercial DSCCs.
