Optical frequency combs are typically generated in the near-infrared wavelength range, where many mode-locked lasers operate. Nonlinear frequency conversion can then be used to extend optical frequency metrology to other spectral regions, such as the

Laser shock peening (LSP) is a mechanical surface treatment process to modify near-surface material properties. Compared to conventional shot peening (SP) the process parameters can be finely adjusted with greater precision and a higher penetration d

Coherently enhancing laser pulses in a passive cavity provides ideal conditions for high-order harmonic generation in a gas, with repetition rates around 100 MHz (refs 1,2,3). Recently, extreme-ultraviolet radiation with photon energies of up to 30 e

Today, ultra-short laser pulses have found widespread applications in metrology, atomic, molecular, solid-state, plasma and nuclear physics. Ultra-precise machining of nearly every material is possible based on an almost non-thermal processing. Pumpi

We demonstrate nonlinear pulse compression by multi-pass cell spectral broadening (MPCSB) from 860 fs to 115 fs with compressed pulse energy of 7.5 µJ, average power of 300 W and close to diffraction-limited beam quality. The transmission of the com

High harmonic generation (HHG) at multi-megahertz pulse repetition rates is challenging, since pulse energy is several orders of magnitudes lower for such lasers than for those conventionally used for the HHG: micro-joules instead of milli-joules. Ho
