WebWe investigated the giant resonance in xenon by high-order harmonic generation spectroscopy driven by a two-color field. The addition of a nonperturbative second harmonic component parallel to the driving field breaks the symmetry between neighboring subcycles resulting in the appearance of spectral caustics at two distinct cutoff energies. … WebA high-quality plasmon-fiber cavity in a doubly resonant configuration can exhibit second-harmonic generation ... a high-quality (Q ≈ 160) resonance can be achieved in combination with a single gold ... a giant SH response with conversion efficiency up to 1.6 × 10-5 is detected upon a pump intensity of 5 × 10 8 W/cm 2 for 100 fs pump pulses ... small wiley期刊
