Microwave Absorption of Surface-State Electrons on Liquid $^3$He

, 2007
We have investigated the intersubband transitions of surface state electrons (SSE) on liquid $^3$He induced by microwave radiation at temperatures from 1.1 K down to 0.01 K.

kHz-order linewidth controllable 1550 nm single-frequency fiber laser for coherent optical communication.

Optics Express, 2017
A kHz-order linewidth controllable 1550 nm single-frequency fiber laser (SFFL) is demonstrated for the first time to our best knowledge. The control of the linewidth is realized by using a low-pass filtered white Gaussian noise (WGN) signal applied on a ...

INVESTIGATION OF ANGULAR AND TEMPERATURE DEPENDENCE OF SPIN-WAVE RESONANCE SPECTRA IN MULTILAYER MAGNETIC FILMS

EPJ Web of Conferences, 2018
In this letter we study the dependences of the resonance field Hn and the linewidth 2ΔHn of the spin-wave resonance (SWR) modes in two-layer ferrite-garnet films with dissipative and mixed spinpinning mechanisms.

Tunable Narrow-Linewidth Si₃N₄ Cascaded Triple-Ring External-Cavity Semiconductor Laser for Coherent Optical Communications

Photonics
We propose an external-cavity laser that combines wide tunability with narrow linewidth. The design utilizes a low-loss Si3N4 waveguide and a thermally tuned cascaded triple-ring resonator to enable continuous wavelength tuning. The numerical simulations

Pump-induced stimulated superradiant Smith-Purcell radiation with ultra-narrow linewidth

eLight
Lasers with the gain medium of gas, liquid, semiconductor, and solid could generate coherent light with rather narrow spectral linewidth, which play an important role in the fields of communication, measurement, sensing, and so on. Although free electron

1970 W 1030 nm Single-Mode All-Fiber Master Oscillator Power Amplifier with ~3.2 GHz Linewidth Based on Ultra-Low NA Active Fiber

Photonics
A high-power narrow-linewidth fiber laser with single-mode beam quality is experimentally demonstrated. By employing a cascaded phase modulation strategy, the stimulated Brillouin scattering (SBS) threshold of the laser is effectively increased from 973 ...
