Narrow-linewidth fiber laser operating at 155 μm [PDF]
We report the fabrication and operation of an Er(3+)-doped silica single-mode fiber laser operating at 1.55 microm and using a distributed fiber grating to provide feedback. The output bandwidth was measured as 0.04 nm, significantly narrower than the conventional cavity design. The laser had a threshold of 13 mW and a slope efficiency of 5%.

Intrinsic cascade-free intramode scattering Brillouin laser
The cascade operation of Brillouin lasers (BLs) is an identified obstacle to single-frequency power scaling and further compression of the fundamental linewidth.

Optical parametric oscillators : a comparison of new materials [PDF]
A study of new materials for optical parametric oscillators (OPOs) was carried out using an XeCI excimer laser as a pump source. The three non-linear optical materials studied were lithium borate (LBO), deuterated L-arginine phosphate (d-LAP) and β ...

Narrow-linewidth tin-vacancy centers in a diamond waveguide
Integrating solid-state quantum emitters with photonic circuits is essential for realizing large-scale quantum photonic processors. Negatively charged tin-vacancy (SnV$^-$) centers in diamond have emerged as promising candidates for quantum emitters ...

An Ultra-narrow-linewidth Microlaser for Nanosensing [PDF]
We report the detection of 11.5-nm radius polystyrene beads in an aqueous environment at a signal-to-noise-ratio of 18:1 by monitoring the split frequency steps of a 5.7-KHz-linewidth microlaser. The thermal-optical effect is also observed.

A tunable and narrow-bandwidth Q-switched ytterbium-doped fiber (YDF) laser is investigated in this paper. The non-pumped YDF acts as a saturable absorber and, together with a Sagnac loop mirror, provides a dynamic spectral-filtering grating to achieve a

Multiwatts narrow linewidth fiber Raman amplifiers
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.
