Active Faraday optical frequency standards [PDF]

open access: yes, 2014
We propose the mechanism of active Faraday optical clock, and experimentally demonstrate active Faraday optical frequency standards based on 852 nm narrow bandwidth Faraday atomic filter by the method of velocity-selective optical pumping of cesium vapor.

Frequency stabilization of an ultraviolet semiconductor disk laser [PDF]

open access: yes, 2013
We report a tunable, narrow-linewidth UV laser based on intracavity second-harmonic generation in a red semiconductor disk laser. Single-frequency operation is demonstrated with a total UV output power of 26 mW. By servo-locking the fundamental frequency

Narrow linewidth, single frequency semiconductor laser with a phase conjugate external cavity mirror [PDF]

open access: yes, 1986
We measure the spectral characteristics of an external cavity semiconductor laser which uses a phase conjugate mirror for its external reflection. This device has significant advantages over the conventional external cavity system owing to the self ...

1.55 μm Narrow-Linewidth Pulsed Laser Based on MgO:PPLN

open access: yesPhotonics, 2023
A high-power narrow-linewidth 1.55 μm pulsed laser, based on MgO:PPLN OPO, has been achieved using a F–P etalon. The pump source is a 1064 nm acousto-optical (AO) Q-switched Nd:YAG laser with a repetition rate of 10 kHz.

Spectroscopic applications and frequency locking of THz photomixing with distributed-Bragg-reflector diode lasers in low-temperature-grown GaAs [PDF]

open access: yes, 1997
A compact, narrow-linewidth, tunable source of THz radiation has been developed for spectroscopy and other high-resolution applications. Distributed-Bragg-reflector (DBR) diode lasers at 850 nm are used to pump a low-temperature-grown GaAs photomixer ...

Intrinsic cascade-free intramode scattering Brillouin laser

open access: yesAPL Photonics, 2023
The cascade operation of Brillouin lasers (BLs) is an identified obstacle to single-frequency power scaling and further compression of the fundamental linewidth.

Theory of linewidth narrowing in Fano lasers

open access: yesPhysical Review Research, 2022
We present a general theory for the coherence of Fano lasers based on a bound state in the continuum. We find that such lasers enable orders of magnitude reduction of the quantum-limited linewidth, and by introducing mirror symmetry breaking, the linewidth can be further reduced.

Cost efficient narrow linewidth laser transmitter for coherent detection [PDF]

open access: yes, 2008
Authors present a cost efficient narrow linewidth laser transmitter for future coherent detection systems. The spectral purity of the laser allows the phase modulation of data signals at bit rates as low as 155 Mb ...

Multiwatts narrow linewidth fiber Raman amplifiers

open access: yesOptics Express, 2008
Up to 4.8 W, approximately 10 MHz, 1178 nm laser is obtained by Raman amplification of a distributed feedback diode laser in standard single mode fibers pumped by an 1120 nm Yb fiber laser. More than 10% efficiency and 27 dB amplification is achieved, limited by onset of stimulated Brillouin scattering.
