Amplifier/compressor fiber Raman lasers
Annual Meeting Optical Society of America, 1987When pump and Stokes pulses copropagate in a fiber Raman laser (FRL), the weaker Stokes spectrum is severely broadened through pump-induced cross-phase modulation (XPM).1 Thus, in an FRL during Raman amplification, the pulse is chirped through XPM, and then the linear anomalous dispersion of a fiber can compress the pulse.

Raman fiber distributed feedback lasers
Optics Letters, 2011We demonstrate fiber distributed feedback (DFB) lasers using Raman gain in two germanosilicate fibers. Our DFB cavities were 124 mm uniform fiber Bragg gratings with a π phase shift offset from the grating center. Our pump was at 1480 nm and the DFB lasers operated on a single longitudinal mode near 1584 nm.

Statistics of a turbulent Raman fiber laser
Optics Letters, 2015We report the experimental study of statistical properties of partially coherent waves emitted by a Raman fiber laser operating in the normal dispersion regime. Using an asynchronous optical sampling technique, we accurately measure the probability density function of the optical power of the Stokes wave that exhibits strong and fast fluctuations.

Characteristics of a fiber-optic Raman laser
Applied Optics, 1977The frequency spectrum of a continuous wave fiber-optic Raman laser is measured and observed to consist of several discrete lines covering a 3-nm spectral range. The output of the laser also contains damped transients which are attributed to strong pump-depletion effects in the fiber. Previously observed degradation of the fiber has been reduced in the

Fiber and Integrated Optics, 1979
Optical fibers can exhibit wavelength conversion and other nonlinear optical effects at powers less than one watt. The reason has little to do with the glass in the fiber core, which is one of the least nonlinear of all materials, but rather with the tremendous interaction length possible in low-loss fibers.

Random fiber Bragg grating Raman fiber laser
Optics Letters, 2014We demonstrate for the first time to our knowledge a Raman random fiber laser (RRFL) based on a long random fiber Bragg grating (RFBG-RRFL). Unlike other recently demonstrated random fiber lasers that rely on incoherent Rayleigh scattering feedback, the present scheme uses randomly distributed phase shifts inside a fiber-meter long Bragg grating as a ...

The use of stimulated Raman scattering (SRS) as a means of amplifying signals in telecommunication systems has been demonstrated since 1976 [1]. Yet despite its advantages over erbium-doped fiber, Raman amplification was not used in the first generation of deployed optically amplified systems.

All-fiber gas Raman laser oscillator
Optics Letters, 2021Here, we report the first, to the best of our knowledge, all-fiber gas Raman laser oscillator (AFGRLO), which is formed by fusion splicing solid-core fibers and a hydrogen-filled hollow-core photonic crystal fiber, and further introducing fiber Bragg gratings at a Stokes wavelength.

Fiber Raman soliton laser pumped by a Nd:YAG laser
Optics Letters, 1987We have pumped a fiber Raman laser with a continuous-wave mode-locked Nd:YAG laser operating at 1319 nm and generated pulses as short as 160 fsec by using soliton pulse shaping in the fiber. We have also constructed a completely integrated oscillator loop by using a fiber-optic coupler and fusion splicing.
