We report on the development of new state-of-the-art ultralow-loss hollow-core fibers guiding in the short-wavelength range. The new record low attenuation values are as low as 50.0 dB/km at 290 nm, 9.7 dB/km at 369 nm, 5.0 dB/km at 480 nm, 0.9 dB/km at 558 nm, and 1.8 dB/km at 719 nm. Notably, the core roughness levels of the new state-of-the-art fibers are under the thermodynamic equilibrium limit set by the surface capillary waves scenario in amorphous silica.

We introduce a geometric representation that we call the Poincaré sphere of electromagnetic coherence. Our model intuitively illustrates the state of coherence and polarization of electromagnetic beams, and it is the first construction that displays optical coherence graphically.

Sub-2 Cycle carrier-envelope-phase–stabilized 110W, 1.1mJ laser

We present a sub-2 cycle laser system combining high average power, pulse energy and repetition rate with CEP-stable operation. The system is based on an 8-channel fiber-based chirped pulse amplification system. The latter emits 300fs pulses, which are post-compressed down to the few-cycle regime in a two-stage multi-pass cell (MPC) nonlinear pulse compression. Furthermore, stabilization of the carrier-to-envelope phase is presented. This unique combination of high average power (110W), pulse energy (1.1mJ), pulse repetition rate (100kHz) and CEP stability makes this system an ideal driver for next generation attosecond sources.

Continuous evolution of non-cyclic Pancharatnam-Berry phase in double-pinhole experiment

We demonstrate a way to measure a continuous evolution of non-cyclic Pancharatnam-Berry phase, using a modified Young’s double-pinhole arrangement, and derive an analytical expression for the phase by employing the geometry of the Poincaré sphere. The measurements and expression match the geodesic rule previously put forward and converge to the cyclic Pancharatnam-Berry phase after a full loop.
