Hyperspectral imaging can reveal the slightest difference in the spectral response of seemingly identical inks. We have studied the reflectivity of the fundamental colors used in inkjet printers, and found distinctive spectral features depending on t

A high harmonics source is used to perform x-ray resonant magnetic scattering on magnetic samples. The dynamics of laser-induced ultrafast demagnetization are probed and longer pump wavelengths are found to increase the initial quenching levels.

We demonstrate 33-fold pulse compression employing a 6-m-long hollow-core fiber and chirped mirrors. 1 mJ, 170 fs pulses at 1030 nm are compressed to 5.1 fs (1.5 optical cycles) with 70% efficiency.

Owing to the increasing significance of high harmonic generation (HHG) as a tabletop coherent x-ray source and the coming of age of intense infrared (IR) lasers, the development of high brightness soft x-ray beamlines is gaining a lot of attention. W
