Nanoscale amplification of non-linear processes in solid-state devices opens novel
applications in nano-electronics, nano-medicine or high energy conversion for example.
Coupling few nano-joules laser energy at a nanometer scale for strong field physics is
demonstrated. We report enhancement of high harmonic generation in nano-structured
semiconductors using nanoscale amplification of a mid-infrared laser in the sample rather
than using large laser amplifier systems. Field amplification is achieved through light …
