Laser-plasma acceleration (LPA) is a compact technique to accelerate electron bunches highly relativistic energies, making it promising candidate power radiation sources for industrial or medical applications. We report on the generation of beams from an 80 MeV-level LPA setup based ionisation injection (II) over duration 8 hours at repetition rate 2.5 Hz, resulting in 72,000 consecutive shots ...

Laser cavity-solitons can appear in systems comprised of a nonlinear microcavity nested within an amplifying fiber loop. These states are robust and self-emergent constitute attractive class solitons that highly suitable for microcomb generation. Here, we present detailed study the free-running stability properties carrier frequency repetition rate single solitons, which most developing ultrafa...

We study the dynamics and bifurcations of a semiconductor laser with delayed filtered feedback, where a part of the output of the laser re-enters after spectral filtering. This type of coherent optical feedback is more challenging than the case of conventional optical feedabck from a simple mirror, but it provides additional control over the output of the semiconductor laser by means of choosin...

A prototype laser distance interferometer is demonstrated by incorporating the frequency comb of a femtosecond laser for mass-production of optoelectronic devices such as flat panel displays and solar cell devices. This comb-referenced interferometer uses four different wavelengths simultaneously to enable absolute distance measurement with the capability of comprehensive evaluation of the meas...
