We successfully demonstrate the generation of an all-solid-state deep-ultraviolet (DUV) laser at 206 nm through the fifth (4 + 1)-harmonic generation using a 197-W, 10-kHz, 1.2-ps, 1,030-nm Yb:YAG laser. The DUV laser delivers 180 μJ–582 fs pulses

High energy pulse self-compression in a hollow core waveguide filled with noble gases has been under intensive study. Here, its dependence on the input pulse group delay dispersion (GDD) and third order dispersion (TOD) is studied experimentally. Pul

Hollow core waveguides are widely used in extreme field research to guide laser pulses. The laser peak intensity is usually several orders higher than the damage threshold of waveguide cladding material in these applications. The nonlinear drift of t

Self-compression of an ultrashort pulse in a hollow-core waveguide filled with noble gas is a simple and promising approach to generate few and even single-cycle pulses. However, when the input pulse energy approaches to mJ level, ionization of the g

The use of chirped quasi-phase-matching (CQPM) for cascaded harmonic generation (CHG) in a single crystal has gained attraction in recent years. CHG involves multiple stages of second harmonic and sum frequency generation processes, of which their co

Self-compression of pulses was observed in gas-filled waveguide. This can be used to enhance High Harmonic Generation (HHG). Here, 2cm hollow waveguide with inner diameter 150μm was used. Bright HHG in water window was produced.

We experimentally observe strong modulation of HHG spectrum in a gas mixture. Calculation results show phase of harmonics are contributed by phase-matching and interference effects, resulting in strong spectrum modulation and may benefit tunable XUV
