Compression of Extreme-Ultraviolet Ultrashort Pulses by Grating Configurations

الملخص EN

The design and realization of grating instruments to condition the spectral phase of ultrashort extreme-ultraviolet pulses are discussed.

The main application of such configurations is the temporal compression of pulses by compensating the phase chirp and getting close to the Fourier limit.

We discuss the two configurations useful for the realization of ultrafast grating compressors, namely, the classical diffraction mount and the off-plane one.

The configuration may be applied to free-electron lasers and high-order laser harmonics.
