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

Photonics, 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.

Intrinsic cascade-free intramode scattering Brillouin laser

APL 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.

Passive intrinsic-linewidth narrowing of ultraviolet extended-cavity diode laser by weak optical feedback [PDF]

, 2014
We present a simple method for narrowing the intrinsic Lorentzian linewidth of a commercial ultraviolet grating extended-cavity diode laser (TOPTICA DL Pro) using weak optical feedback from a long external cavity.

Theory of linewidth narrowing in Fano lasers

Physical 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.

Nanosecond channel-switching exact optical frequency synthesizer using an optical injection phase-locked loop (OIPLL) [PDF]

, 2004
Experimental results are reported on an optical frequency synthesizer for use in dynamic dense wavelength-division-multiplexing networks, based on a tuneable laser in an optical injection phase-locked loop for rapid wavelength locking.

Multiwatts narrow linewidth fiber Raman amplifiers

Optics 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.
