Ultrafast Raman fiber Laser with Random Distributed Feedback

Laser & Photonics Reviews, 2018
AbstractUltrafast Raman fiber lasers are wavelength‐agile light sources for various scientific and medical applications. Pulse pumping is an efficient way to generate a high power ultrafast Raman fiber laser, which however requires real‐time synchronization between the pump pulses and laser cavity.

The rising power of random distributed feedback fiber laser

2017 International Conference on Optical Instruments and Technology: Advanced Laser Technology and Applications, 2018
Random distributed feedback fiber lasers (RDFFL) are now attracting more and more attentions for their unique cavity-free, mode-free and structural simplicity features and broadband application potentials in many fields, such as long distance sensing, speck free imaging, nonlinear frequency conversion as well as new pump source.

On-off and multistate intermittencies in cascaded random distributed feedback fibre laser

2013 Conference on Lasers & Electro-Optics Europe & International Quantum Electronics Conference CLEO EUROPE/IQEC, 2013
The paper studies intensity fluctuations in a random DFB fiber laser based on nitrogen doped fiber. The laser generates first and second Stokes components 1120 nm and 1180 nm respectively under an appropriate pumping. This work studies the intermittency in the radiation of the second Stokes wave.

Distributed feedback and random lasing in DCNP aggregates dispersed in a polymeric layer

Optics Letters, 2015
Here, we report on the realization of random lasing (RL) and distributed feedback (DFB) lasing in a layer of luminescent 3-(1,1-dicyanoethenyl)-1-phenyl-4,5-dihydro-1H-pyrazole (DCNP) organic nonlinear optical dye that has been dispersed in a poly(methyl methacrylate) (PMMA) matrix.

Narrow-band Radiation in the Random Distributed Feedback Fiber Laser

European Conference and Exhibition on Optical Communication, 2012
Narrow-band generation is achieved in random distributed feedback (RDFB) fiber laser by using narrow-band filters in the center of a distributed cavity. The resulting line-width of ~0.1 nm is 10 times less than line-width in classical random distributed feedback fiber laser. Spectral properties can be optimized further.

New schemes of Raman fiber lasers with random distributed feedback

CLEO Pacific Rim Conference, 2018
Fiber lasers have been actively developed in the last decade demonstrating unique efficiency and performance. It is known that the laser generation is possible not only in active fibers, but also in passive fibers owing to the effect of stimulated Raman scattering (SRS).
