Advances in narrow linewidth diode lasers [PDF]

SCIENTIA SINICA Informationis, 2019
The era of smart travel has arrived, and the need for high precision lidar detection technology is increasing. With the advantages of high resolution, a strong anti-active jamming ability, small volume, light weight, and low cost, new solid-state lidars can meet the requirements of intelligent cars in the future.

Narrow-Linewidth 852-nm DBR-LD with Self-Injection Lock Based on High-Finesse Optical Cavity Filtering

Photonics, 2023
Narrow-linewidth lasers have a high spectral purity, long coherent length, and low phase noise, so they have important applications in atomic clocks, precision measurement, and quantum computing. We inject a transmitted laser from a narrow-linewidth (∼15

Low-noise Brillouin laser on a chip at 1064 nm [PDF]

, 2014
We demonstrate narrow-linewidth-stimulated Brillouin lasers at 1064 nm from ultra-high-Q silica wedge disk resonators on silicon. Fundamental Schawlow–Townes frequency noise of the laser is on the order of 0.1  Hz^2/Hz.

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)

Longitudinal modes in a high-gain laser [PDF]

, 1970
In lasers employing high-gain narrow-linewidth transitions the theory predicts major departures of the mode-splitting frequencies from their low-gain values as well as a new type of mode splitting.

A Compact Self-Injection-Locked Narrow-Linewidth Diode Laser with Narrowband Dielectric Filter

Applied Sciences, 2023
The self-injection-locked diode laser can significantly reduce the linewidth down to a sub-100 kHz level but requires optical filtering that is much narrower than the laser cavity linewidth.

Two-Color Magneto-Optical Trap with Small Magnetic Field for Ytterbium [PDF]

, 2015
We report a two-color magneto-optical trap (MOT) for ytterbium atoms operating at a low magnetic field gradient down to 2 G/cm where a conventional MOT using the singlet transition (6s^2 1S0 -> 6s6p 1P1) is unable to trap atoms.
