Attosecond lighthouse driven by sub-two
... High-order harmonic generation, the nonlinear interaction between intense laser pulses and an ionizing medium, produces bursts of coherent XUV emission with attosecond pulse duration [1]. These attosecond pulses make the study and control of ultrafast electron dynamics [2] possible up to a time scal ...

... In the Fabry–Perot laser cavity The light makes two passes through the gain medium per round-trip (RT). Laser system consists of a set of mirrors and a gain medium. The gain medium is an optical amplifier which coherently amplifies light passing through it. The mirrors may be curved or planar and to ...

... Why? No interference between paths leading to different frequencies at the detectors, because in principle one could go back and measure how much energy had been absorbed. Note: it took a long time-integral to enforce this. If the detector had been open only for 1 fs, it would be impossible to tell ...
