Recent progress in high-order harmonic generation with few-cycle mid-infrared wavelength lasers has pushed light pulses into the water-window region and beyond. These have bandwidth to support single attosecond down a few tens of attoseconds. However, present available techniques for pulse measurement are not applicable such pulses. Here we report phase-retrieval method using standard photoelectron streaking technique where an is converted its electron replica through photoionization atoms...

Throughout the development of single frequency fiber lasers (SFFLs), gain is one most important components, which can greatly affect quality SFFLs. Here, we fabricated an Er: YAG crystal-derived silica (EYDSF) using a CO2 laser-heating drawing technique, with high coefficient 1.74 dB/cm. Employing EYDSF only 10 cm as medium, constructed continuous-wave ring-cavity SFFL all-fiber system. An ultra-narrow linewidth <660 Hz was achieved harnessing homemade low-concentration Er-doped saturable...

Based on its ultra-low backscattering characteristic, anti-resonant hollow-core fiber is a good medium for bidirectional transmission, which means that the wavelengths of transmission channels are same in both directions. In this Letter, we present first, to best our knowledge, demonstration S + C L-band same-wavelength an fiber. By using commercial real-time coherent optical transceivers and amplified spontaneous emission (ASE) source, total net throughput 273.6 Tbit/s achieved over 1.4 km...

This paper reports the results of a full-scale field test that was conducted to assess performance use wet-milling cement and chemical compound grouting in same hole reinforce flexural fracture zone. Wet-milling methods were used treat layer zone with thickness 19 m. The procedures cement–chemical method described detail, normal water pressure test, fatigue failure shear wave velocity suggested working effects epoxy testing area better than those acrylic acid salt area, which further...

We report an all-optical radio-frequency (RF) spectrum analyzer with a bandwidth greater than 5 terahertz (THz), based on 50-cm long spiral waveguide in CMOS-compatible high-index doped silica platform. By carefully mapping out the dispersion profile of waveguides for different thicknesses, we identify optimal design to achieve near zero C-band. To demonstrate capability RF analyzer, measure optical output femtosecond fiber laser ultrafast regime.

We propose a method for the selective generation of high-order orbital angular momentum (OAM) modes by twisting ring-core fiber (RCF). Theoretically, 22 OAM can be generated in twisted RCF with effective mode separation. experimentally demonstrate excitation up to fourth order. The positive or negative topological charge is determined clockwise counterclockwise twist direction, indicating that helical phase controlled orientation. Compared other fiber-based methods, our approach have...

We fabricate two Bi/Er/La co-doped silica fibers (BELDFs). With the high-concentration doped BELDF, fluorescence-spectrum bandwidth of intensity >−35 dBm reaches 75 nm (1548-1623 nm), and based on a dual-pump system, gain-spectrum gain >17 dB is up to 58 (1565-1623 nm). Then, dual-stage triple-pump amplification investigated, from which L-band could be extended 1625 with over 16 dB, reach (1562-1620 nm) >25 dB. The results indicate that utilizing homemade BELDF can become an effective way...

Abstract Interspecies chimera formation with human pluripotent stem cells (PSCs) holds great promise to generate humanized animal models and provide donor organs for transplant. However, the approach is currently limited by low levels of ultimately represented in chimeric embryos. Different strategies have been developed improve chimerism genetically editing PSCs. To date, however, it remains unexplored if can be enhanced animals through modifying host Leveraging interspecies PSC competition...
