A Decade of Sub‐100‐fs Thin‐Disk Laser Oscillators
Laser &Photonics Reviews, Volume 17, Issue 8, August, 2023., 2023 A decade has passed since the first demonstration of a sub‐100‐fs thin‐disk laser oscillator. Ever since, the technology has strived to become a 100‐W‐class single‐stage laser system capable of delivering sub‐100‐fs pulses directly from the oscillator without the requirement for chirped pulse amplification or nonlinear postcompression.

Femtosecond Frequency Combs with Few‐kHz Passive Stability over an Ultrabroadband Spectral Range
Laser &Photonics Reviews, Volume 17, Issue 7, July 2023., 2023 The noise properties of fiber‐based frequency combs are studied in a wide parameter range. In specific regions, the free‐running linewidth of the carrier‐envelope offset frequency drops below 1 kHz. All relevant contributions to the phase noise and their interplay are identified.

Recent advanced applications of metasurfaces in multi‐dimensions
Nanophotonics, Volume 12, Issue 13, Page 2295-2315, June 2023., 2023 Abstract Unlike traditional optical components, which rely on the gradual accumulation of light along the optical path over a distance much larger than the wavelength to form a wavefront, metasurfaces manipulate light field properties on the wavelength thickness by specially arranging various meta‐atoms.

Advanced Optical Materials, Volume 10, Issue 22, November 18, 2022., 2022 A gate‐tunable single‐layer graphene embedded in a quarter‐wave cavity behaves as a terahertz (THz) compact amplitude modulator, saturable absorber, and frequency tuner. Electrolyte ionic liquid gating ensures 40% modulation depth and 60% reflectivity modulation with ≈4.5 W cm−2 saturation intensity. Fine‐tuning of the intermode beatnote frequency of a
