Narrow-linewidth single-polarization fiber laser using non-polarization optics.
Optics Letters, 2021Single longitudinal mode and single polarization are basic requirements of high performance fiber lasers, while their realizations are nontrivial, owing to the long laser cavity and lack of polarization selection of ordinary optical fibers.

Narrow linewidth quantum cascade laser
Conference on Lasers and Electro-Optics, 2020A narrow linewidth quantum cascade laser was obtained by optical feedback locking to a high finesse linear cavity with locking bandwidth larger than 5 MHz, resulting in an instantaneous linewidth at mHz levels.

Narrow linewidth unstable resonators
Annual Meeting Optical Society of America, 1988We have previously demonstrated that a feedback ring in an unstable resonator can be useful in providing narrow bandwidth radiation across the full available aperture of the resonator. In this configuration the light traveling in the forward direction in the ring passes through frequency-narrowing etalons while it is collimated and is then coupled back

Wavelength-tunable narrow-linewidth gaseous Raman laser
Applied Optics, 2021Gaseous Raman lasers cover a range of wavelengths but lack wavelength tunability. Here, a 1 c m − 1 linewidth 532 nm laser was used as a pump laser, and with a narrow-linewidth seed laser injection, a narrow-linewidth first Stokes (S1) Raman ...

Waveguide external cavity narrow linewidth semiconductor lasers
, 2021Narrow linewidth light source is a prerequisite for high-performance coherent optical communication and sensing. Waveguide-based external cavity narrow linewidth semiconductor lasers (WEC-NLSLs) have become a competitive and attractive candidate for many

Narrow linewidth single frequency microfiber laser
Optics Letters, 2012A compact 2 kHz linewidth single frequency microfiber ring laser is demonstrated. Microfiber, with a diameter of 1.88 μm, which is drawn from an Er(3+)/Yb(3+) co-doped phosphate glass fiber, serves as the gain medium. By using this microfiber, a double-knot resonator with a total length of 1.75 mm is constructed.

Modulatable narrow-linewidth semiconductor lasers
Applied Physics Letters, 1988We find that using the technique of optical feedback locking, to narrow semiconductor linewidths, does not sacrifice the ability to modulate the laser’s frequency via the injection current. The frequency of a laser is stabilized to a separate Fabry–Perot reference cavity using resonant optical feedback and can be modulated efficiently at frequencies ...
