Abstract

Many intriguing phenomena in nature - from phase transitions to black holes - occur at singularities. A unique type of singularity common in wave phenomena, known as caustics^1,2, links processes observed in many different branches of physics^3,4. Here, we investigate the role of caustics in attosecond science and in particular the physical process behind high harmonic generation⁵. We experimentally demonstrate spectral focusing in high harmonic generation, showing a robust intensity enhancement of an order of magnitude over a spectral width of several harmonics. This new level of control holds promises in both scientific and technological aspects of attosecond science^6,7. Moreover, our study provides a deeper insight into the basic mechanism underlying the high harmonic generation process, revealing its quantum nature⁸ and universal properties.
