The generation of extremely short isolated attosecond pulses requires both a broad spectral
bandwidth and control of the spectral phase. Rapid progress has been made in both …

Ultrafast optical parametric amplifiers (OPAs) can provide, under suitable conditions, ultra-
broad gain bandwidths and can thus be used as effective tools for the generation of widely …

Attosecond metrology has so far largely remained limited to titanium: sapphire lasers
combined with an active stabilization of the carrier-envelope phase (CEP). These sources …

The emission of coherent XUV radiation from atomic or molecular gases exposed to intense
infrared laser pulses, known as high harmonic generation, is of paramount interest in atomic …
