Invited talk

Single-frequency fiber lasers have advantages such as high power, broad spectral coverage, excellent beam quality, and good robustness. During the development of 589 nm sodium guide star lasers for astronomical adaptive optics, our team has developed key technologies including high-power single-frequency fiber amplifiers, ultra-broadband wavelength tuning of fiber lasers, and high-efficiency...

High-power single-frequency continuous-wave lasers are essential for a range of applications in precision spectroscopy, metrology, optical clocks, and quantum technologies. However, achieving stable single-frequency operation at high power is often challenging because nonlinear optical processes can generate unwanted frequency components that degrade spectral purity and stability. In...

Both short- and long-haul communication networks rely on optical fibres to satisfy the continually increasing demand for data capacity and transmission speed. In short-reach links, such as those within and between data-centre racks, vertical-cavity surface-emitting lasers (VCSELs) are commonly paired with multimode fibres (MMFs) to transmit binary data as rapidly modulated optical...

Fractional derivatives, and particularly fractional Laplacian operators, have been studied intensively in physics, mathematics and engineering [1]. In optics, such operators offer a route to generalize the conventional nonlinear Schrödinger equation by replacing the usual quadratic dispersion with a fractional dispersion law. The fractional Laplacian operator is written as...
