Ho:YAG laser at 2097 nm pumped by a narrow linewidth tunable 1.91 μm laser
This study presents a high efficiency Ho:YAG laser based on a narrow linewidth tunable 1 91 μm laser A tunable Tm:YLF laser is the pump source and the wavelength continuous tunability ranges from 1906 04 to 1908 83 nm, corresponding to a linewidth of l
Mid-infrared electronic wavelength tuning through intracavity difference-frequen
Mid-infrared tunable coherent light sources are used in various laser applications, such as trace gas detection, laser processing, and biomedical diagnostics This study demonstrates mid-infrared
The first chip-scale titanium-doped sapphire laser has been developed by a research team at Yale University Led by Professor Hong Tan, this experimental breakthrough could pave the way for new innovations in atomic clocks, quantum technology and spectros
400 W average power Q-switched Yb:YAG thin-disk-laser
We report on producing up to 403 W average power directly from an acousto-optically Q-switched Yb:YAG thin-disk laser (TDL) To achieve this power, it has theoretically and experimentally been shown that the laser stability border could be shifted toward
Single-frequency fiber lasers using rare-earth-doped silica
Commercial silica fibers doped with ytterbium and erbium achieve sufficient gain to enable fabrication of distributed Bragg reflector single-frequency fiber lasers
Scientists propose revolution in complex systems modeling with quantum technolog
Scientists have made a significant advancement with quantum technologies that could transform complex systems modeling with an accurate and effective approach that requires significantly reduced memory
In-fibre second-harmonic generation with embedded two-dimensional materials -II
Although bulk silica itself has zero second-order susceptibility, there is a minor contribution stemming from the surface of the ECF core This surface imposes symmetry breaking perpendicular to the optical axis, which, in turn, leads to SHG We use the S
In-fibre second-harmonic generation with embedded two-dimensional materials
Silica-based optical fibres are a workhorse of nonlinear optics, providing ready access to a range of nonlinear phenomena including solitons and self-phase modulation However, they have one fundamental limitation: due to the amorphous nature of silica, t
High-Performance Second-Harmonic-Generation (SHG) Materials: New Developments an
Second-harmonic-generation (SHG) causes the frequency doubling of light, which is very useful for generating high-energy lasers with specific wavelengths Noncentrosymmetry (NCS) is the first requirement for an SHG process because the SHG coefficient is z
The translational Doppler effect of electromagnetic and sound waves has been successfully applied in measurements of the speed and direction of vehicles, astronomical objects and blood flow in human bodies1,2,3,4,5,6,7,8, and for the Global Positioning Sy
