Multicolor wavefront sensing using Talbot effect for high-order harmonic generation

Physical Review Research
High-order harmonic generation (HHG) using femtosecond lasers is an efficient and cost-effective method for producing attosecond and femtosecond light in the extreme ultraviolet and soft x-ray regions.

Near-circularly polarized isolated attosecond pulse generation from gas mixture with two-color multicycle laser fields

Results in Physics
We theoretically demonstrate a scheme for efficiently generating near-circularly polarized isolated attosecond pulses from mixed gases driven by non-integer frequency ratio two-color multicycle laser fields.

Generation of squeezed high-order harmonics

Physical Review Research
For decades, most research of high harmonic generation (HHG) considered matter as quantum but light as classical. Recently, HHG driven by quantum states of light such as bright squeezed vacuum was predicted to reach beyond the classical HHG cutoff. Moreover, in squeezed coherent illumination, it was shown that the underlying dynamics are significantly ...

Intracavity generation of high order harmonics

, 2011
The goal of this work is the generation of extreme ultraviolet (EUV) radiation from a laser based source. To this end, we use high harmonic generation (HHG) to convert the near infrared output of a mode-locked Ti:Sapphire laser oscillator to the EUV.

Coherent harmonic generation of magnons in spin textures

Nature Communications
Harmonic generation, a notable non-linear phenomenon, has promising applications in information processing. For spin-waves in ferromagnetic materials, great progress has been made in the generation higher harmonics, however probing the coherence of these
