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.

Progress and trend of narrow-linewidth lasers

Science China Technological Sciences, 2013
High frequency stability, narrow-linewidth lasers have been long dreamed of since the invention of the laser. They have recently developed dramatically due to the advent of optical clocks. State-of-the-art narrow-linewidth lasers have been constructed by using the Pound-Drever-Hall (PDH) technique to lock the laser frequencies to the resonance of ultra-

Narrow-Linewidth Fano Laser

Conference on Lasers and Electro-Optics, 2022
By exploiting Fano resonances, a microscopic laser with a linewidth >20 times smaller than previous microscopic lasers is experimentally demonstrated. We also show that the linewidth can be further improved by engineering the Fano lineshape.

Hybrid integrated narrow-linewidth semiconductor lasers

Applied Optics, 2023
Integrated narrow-linewidth lasers are the key devices in compact coherent optical systems of metrology, sensing, and optical microwave generation. Here, we demonstrate a hybrid integrated laser based on an optical negative feedback scheme.

Future Narrow Linewidth Lasers

Optical Fiber Communication Conference, 2015
We describe the challenges and solutions for future narrow linewidth lasers with small footprint. We fabricated DR laser array based narrower linewiedth TLS. We introduce ITXA of a co-packaged DFB array based TLS and InP-based modulator.

Narrow-linewidth unstable resonator

Optics Letters, 1988
We describe the use of an asymmetric feedback ring in an unstable resonator to obtain arbitrarily narrow-linewidth radiation across the full available aperture. We demonstrate its use with an electric-discharge XeCl laser to produce single-line radiation with a linewidth of 0.15 cm−1.

Narrow linewidth unstable resonators

Annual Meeting Optical Society of America, 1988
We have previously demonstrated that a feedback ring in an unstable resonator can be useful in providing narrow bandwidth radiation across the full available aperture of the resonator. In this configuration the light traveling in the forward direction in the ring passes through frequency-narrowing etalons while it is collimated and is then coupled back
