Integrated-optic, narrow-linewidth laser

Applied Physics Letters, 1986
We report the demonstration of the single-frequency and narrow-linewidth (<100 kHz) operation of an extended cavity laser consisting of a Ti:LiNbO3 single-mode waveguide circuit and an InGaAsP waveguide gain medium. A parallel coupled cavity, electro-optic elements for tuning the resonant frequencies of the cavities, and an external phase ...

Near Infrared Ultra-Narrow-Linewidth Laser

Conference on Lasers and Electro-Optics, 2020
We report on self-injection-locked near infrared laser technology using whisper-gallery-mode resonators. The laser linewidth is suppressed by 104 and has an instantaneous linewidth in the sub-10 Hertz range. The laser is used for generating stable reference light for atomic clocks.

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), 2016
A 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.

Narrow-linewidth tunable ArF* excimer-laser source

IEEE Journal of Quantum Electronics, 1981
The 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 ...

Ultra-narrow-linewidth Brillouin/Erbium Fiber Laser

Conference on Lasers and Electro-Optics, 2017
Ultra-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

Narrow-linewidth quantum cascade laser at 86  μm

Optics Letters, 2014
We report on a narrow-linewidth distributed-feedback quantum cascade laser at 8.6 μm that is optical-feedback locked to a high-finesse V-shaped cavity. The spectral purity of the quantum cascade laser is fully characterized using a high-sensitivity optical frequency discriminator, leading to a 1 ms linewidth of less than 4 kHz and a minimum laser ...

High power, narrow linewidth fiber lasers

SPIE Proceedings, 2006
Single transverse mode fiber lasers have recently achieved output powers at the kilowatt level. These breakthroughs can be attributed to the maturation of high power diode pump technology at 980 nm and the use of large mode area (LMA) fibers. In the continous wave (cw) operation regime, LMA fibers, through their reduction of device length and increase ...

Narrow-Linewidth Lasers on a Silicon Chip

2014
Diode-pumped distributed-feedback (DFB) channel waveguide lasers were demonstrated in Er3+-doped and Yb3+-doped Al2O3 on standard thermally ox-idized silicon substrates. Uniform surface-relief Bragg gratings were patterned by laser-interference lithography and etched into the SiO2 top cladding. The maxi-mum grating reflectivity exceeded 99%. Monolithic
