Narrow linewidth, tunable distributed feedback photodetector

Applied Physics Letters, 1996
We demonstrate a photodetector with a narrow spectral linewidth (approximately 2 Å) and a useful electrical-tuning range of 35 Å. The photodetector features a horizontal resonant cavity in which feedback is achieved using distributed feedback reflectors. The optical and electrical paths in this photodetector are orthogonal.

Narrow-linewidth external-cavity tunable lasers

10th International Conference on Optical Communications and Networks (ICOCN 2011), 2011
This paper reports our recent work on narrow-linewidth tunable laser, which utilizes two etalons in the external cavity to obtain linewidth 60 dB and fiber-coupled output power > 20 mW. (2 pages)

Narrow linewidth ultraviolet semiconductor disk laser

2013 Conference on Lasers & Electro-Optics Europe & International Quantum Electronics Conference CLEO EUROPE/IQEC, 2013
Here we combine active stabilisation of an AlGaInP-based red semiconductor disk laser (SDL) with intracavity frequency doubling in the same cavity in order to achieve narrow linewidth,

Compact narrow linewidth semiconductor laser module

SPIE Proceedings, 2009
Frequency noise reduction of semiconductor lasers using electrical feedback from an optical frequency discriminator is an efficient and simple approach to realize narrow linewidth lasers. These lasers are of great interest for applications such as LIDAR, RF photonics and interferometric sensing.

Miniature narrow-linewidth 1 μm laser

Applied Physics Letters
A self-injection locking scheme has the potential to narrow the linewidth of lasers in a compact setup. Here, we report a narrow linewidth laser source near 1 μm by the self-injection locking scheme using a Fabry–Pérot (FP) hollow resonator with a high-quality factor (Q > 108).

Compact narrow-linewidth nanosecond Ti:sapphire laser

Journal of Optical Technology, 2017
A compact high peak power tunable narrow-linewidth nanosecond Ti:sapphire laser is presented in this paper. A maximum average output power of 1.4 W with a linewidth of 0.12 nm at 780.21 nm is achieved at a pulse width of 120 ns and a repetition rate of 3 kHz, leading to a peak power of 3.89 kW.

High power narrow linewidth fiber lasers

Optical Amplifiers and Their Applications/Integrated Photonics Research, 2004
Compact, robust, single-frequency fiber lasers, emitting around 1.06 or 1.5 µm with up to several hundred mW power combine polarized output with very narrow linewidth of 1-3 kHz and fast frequency modulation up 10 kHz.
