2.58 kW Narrow Linewidth Fiber Laser Based on a Compact Structure with a Chirped and Tilted Fiber Bragg Grating for Raman Suppression

Photonics, 2021
We report a high power, narrow linewidth fiber laser based on oscillator one-stage power amplification configuration. A fiber oscillator with a center wavelength of 1080 nm is used as the seed, which is based on a high reflection fiber Bragg grating (FBG)

KW narrow linewidth all fiber laser [PDF]

AIP Conference Proceedings, 2019
Recently, high power narrow linewidth fiber lasers are interested in wavelength beam combining. In narrow linewidth fiber laser, Stimulated Brillouin Scattering is the main power limiting factor. A Stimulated Brillouin Scattering suppressing method by modulating frequency distribution was proposed and examined both experimentally and theoretically. The

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

4.68 GHz, 2.35 kW Single Mode All-Fiber Amplifier Using Nonlinear Phase Demodulation for SBS Suppression and Spectral Compression

IEEE Photonics Journal
The output power of fiber lasers with narrow-linewidth is typically limited by stimulated Brillouin scattering (SBS). Spectral broadening via phase modulation is preferred to suppress SBS, but its capability approaches the limit for a given linewidth and

Restoring Narrow Linewidth to a Gradient-Broadened Magnetic Resonance by Inhomogeneous Dressing

, 2019
We study the possibility of counteracting the line-broadening of atomic magnetic resonances due to inhomogeneities of the static magnetic field by means of spatially dependent magnetic dressing, driven by an alternating field that oscillates much faster ...

Narrow-linewidth exciton-polariton laser

Optica
Exciton-polariton lasers are a promising source of coherent light for low-energy applications due to their low-threshold operation. However, a detailed experimental study of their spectral purity, which directly affects their coherence properties, is still missing.
