Summary: We present a widely-tunable mid-infrared picosecond optical vortex laser source, utilizing a synchronized-pumped optical parametric oscillator optimized for emission up to 5 μm in the mid-infrared range. The vortex output with a continuously-tunable wavelength range of 2.6-5 μm can be achieved by translating the MgO:PPLN crystal. At the maximum pump power of 15 W, the measured maximum idler output powers were 3.7 W, 1.7 W, and 0.165 W at wavelengths of 2.6 μm, 3.8 μm, and 5 μm, respectively. The corresponding photon conversion efficiencies were estimated to be 60% at 2.6 μm, 40% at 3.8 μm, and 5.2% at 5 μm.

Summary: Photonic integrated circuits fabricated using a Si3N4 waveguide platform exhibit low losses in a wide wavelength region. A high-performance integrated laser with broad wavelength tunability near a 2.6 μm wavelength region is demonstrated, based on a Si3N4 photonic integrated circuit incorporating a tunable reflector and a AlGaInAsSb/GaSb quantum-well gain element. The platform also supports low propagation loss up to 3.5 μm.

Summary: We have developed a widely tunable mode-locked thulium-doped fiber laser based on a robust chirped fiber Bragg grating (CFBG). By applying mechanical tension and compression, the CFBG achieved an overall tunability of 20.1 nm, ranging from 2022.1 nm to 2042.2 nm. The mode-locked pulse train from this fiber laser has a repetition rate of 9.4 MHz, average power of 12.6 dBm, and pulse duration between 9.0 ps and 12.8 ps. This is the first demonstration of a tunable mode-locked thulium-doped fiber laser operating beyond 2 μm using a CFBG as a wavelength-selective element.

Summary: The introduction of multi-branch repeater laser stations allows the dissemination of an ultra-stable signal to multiple users and evaluation of the stability and accuracy of multiple links simultaneously. A 4800 km optical fiber network with three MLSs and 13 RLSs showed successful multi-user optical frequency dissemination with uncertainties below 1.1 x 10(-19). The network demonstrated robustness over two years and stability and accuracy at 10(7) seconds integration time.
