Recent advances on Ytterbium ultrafast lasers have led to compact and versatile systems with high average output power, potentially high pulse energy and easily tunable repetition rate. Such lasers are well suited for time-resolved pump-probe experiments, a field which involves a wide range of techniques spanning from X-rays diffraction imaging and spectroscopy to asynchronous optical sampling (ASOPS)...
The amazing progress made by high-power ultrafast laser systems in the last decade has revolutionized many fields of science and technology. Nowadays, ultrafast laser systems delivering hundreds of watts of average power with pulse energies ranging from hundreds of microjoules to hundreds of millijoules start to be even commercially available. At the forefront of this progress are core laser technologies...
The generation of extreme-ultraviolet (XUV) isolated attosecond pulses (lAPs) by the process of high harmonic generation (HHG) has enabled the investigation of electronic dynamics in atoms, molecules and solids. Due to limitations in laser technology, the currently available repetition rate of such sources is well below 1 MHz. IAPs at higher repetition rates promise, amongst others, to advance experiments...
The present study is focused on determination of the ablated volume and profile of lines, by femtosecond laser dynamic scanning process. After identification of the laser-matter interaction parameters (w0 — waste size, α−1 — optical penetration depth, Fth — fluence threshold for one pulse) with static shots, experimental and calculated line volume and profiles will be compared. An analytical model...
Upcoming applications in material processing, countermeasures, remote sensing and spectroscopy will rely on the development of simple and reliable sources that generate intense laser pulses in the mid-IR spectral region (3–20 μm). Fiber lasers are certainly among the most promising candidates for such applications. Mid-IR ultrafast fiber lasers have been recently demonstrated using Er3+- and Ho3+-doped...
