The concept of random lasers exploiting multiple scattering of photons in an amplifying
disordered medium in order to generate coherent light without a traditional laser resonator …

Single-frequency operation of a 1.03 μm fiber laser with random distributed feedback
(RDFB) is demonstrated. The laser cavity is based on a 4 cm long fiber Bragg grating (FBG) …

A numerical model for erbium distributed feedback (DFB) fibre lasers is presented. The
model is used to optimise the location of a discrete phase-shift to obtain maximum output …

We analyze the properties of a distributed feedback fiber laser based on Raman
amplification. Such a laser is quite practical and has a number of novel properties. We …

It is a daunting challenge to realize ultraviolet C (UVC) lasing (ie, has a wavelength range
from 200 to 275 nm) from upconversion nanocrystals due to their low upconversion …

Previous theoretical studies of distributed feedback fiber lasers (DFB-FLs) have largely
relied on numerical simulations. In this paper, analytical expressions are derived for the …

The dynamics of erbium distributed feedback fiber lasers close to steady state is analyzed
taking into account spatial hole burning and the nonuniform modefield distribution. A set of …

Fiber lasers with compact cavity have numerous potential applications in sensing,
communications, and medicine. Distributed feedback (DFB) rare-earth doped fiber lasers …

We demonstrated optical amplification at 1550 nm with a carbon tetrachloride solution of Er^
3+-Yb^ 3+ codoped NaYF_4 nanocubes synthesized with solvo-thermal route. Upon …

We present the first observation of optical amplification around∼ 1 μm taking place in
carbon tetrachloride solution of Nd 3+ doped crystal nanoparticle synthesized with solvo …
