A study of narrow linewidth Li-ferrite
IEEE Transactions on Magnetics, 1980Using conventional ceramic procedure and cheap raw materials, we have succeeded in preparing narrow linewidth polycrystalline Li-ferrites with the chemical formula: Li 0.5(1-x+y) Zn x Ti y Fe 2.5-0.5(x+3y)-z Mn z O 4 in the region of 0.15 and observed the growth condition of the grains.

Narrow linewidth tunable semiconductor laser
2016 Compound Semiconductor Week (CSW) [Includes 28th International Conference on Indium Phosphide & Related Materials (IPRM) & 43rd International Symposium on Compound Semiconductors (ISCS), 2016A full-C band tunable laser equipped with an air-gap suspended waveguide structure for efficient thermal heater tuning is described. It is shown that the monolithic tunable laser can simultaneously meet the requirements for the output power, side-mode suppression ratio, and spectral linewidth for 16-QAM coherent communication system.

Integrated Ultra-Narrow Linewidth Stabilized SBS Lasers
Optical Fiber Communication Conference (OFC) 2022, 2022Frequency-stabilized, spectrally-pure lasers are key to precision scientific applications including quantum, atomic clocks, and metrology. We discuss progress towards integrating aspects of these systems to the chip-scale using Si3N4 Brillouin lasers and ultra-high Q resonators.

Narrow-linewidth and tunable parametric oscillator
CLEO 2024We present a tunable coherent oscillator based on parametric gain. It is realized through self-injection locking one comb line of a Kerr microcomb. Sub-Hertz intrinsic linewidth and 20nm tuning range are achieved.

Narrow-linewidth stimulated Brillouin fiber laser and applications
Optics Letters, 1991A stimulated Brillouin fiber ring laser with a spectral width of 2 kHz and an intrinsic linewidth of less than 30 Hz has been demonstrated. Applications of such a laser include laser linewidth narrowing, microwave frequency generation, high-rate amplitude modulation, and optical inertial rotation sensing.

Narrow-linewidth tunable ArF* excimer-laser source
IEEE Journal of Quantum Electronics, 1981The generation of narrow-linewidth tunable radiation from excimer lasers has been a topic of considerable investigation recently.1 Because of the short laser wavelengths generated, such sources are ideal tools for multiphoton spectroscopy in the VUV.2 Because conventional excimer lasers generally operate with broadband laser output and poor beam ...

Narrow linewidth operation of a flashlamp-pumped dye laser
Applied Optics, 1982The authors describe a flashlamp-pumped dye laser system that produces more photons per laser pulse than in nitrogen or Nd:YAG laser-pumped dye lasers. The system uses both a grazing incidence grating and a Littrow mounted grating in conjunction with an elliptical cavity.

Narrow linewidth fibre laser sources [PDF]
, 1990 Laser sources based on rare-earth-doped single-mode optical fibres offer considerable potential as narrow-linewidth sources. Fibre laser sources have the capacity to produce highly-coherent, low-noise output, pumped by laser diodes. Fibre lasers are inherently compatible with optical fibres for transmission and sensing applications.

Ultra-narrow-linewidth Brillouin/Erbium Fiber Laser
Conference on Lasers and Electro-Optics, 2017Ultra-narrow-linewidth lasers are of great interest in many applications, such as precise spectroscopy, optical communications, and sensors. Stimulated Brillouin scattering (SBS), as one of the main nonlinear effects in fibers, is capable of generating narrow-linewidth light emission. We establish a compact Brillouin/erbium fiber laser (BEFL) utilizing
