“…The gain imbalance was significantly improved as the RC-EDF length was shortened, owing to the reduction in the reabsorption effect and absorption. With the 11.5 m RC-EDF, the amplified power was lower than the absorbed power was at the 1530 nm level, which resulted in a negative net gain due to the reabsorption effect [30]. This means that the amplified power under the excessively long RC-EDF was strongly reabsorbed due to the Er 3+ absorption band at around the 1535 nm level.…”

We demonstrated that a ring-core erbium-doped fiber amplifier (RC-EDFA) can support orbital angular momentum (OAM) modes with topological charges (|l| = 1~3). The dependence of the characteristics on the length of the RC-EDF was investigated experimentally, including an investigation of gain and 3 dB gain bandwidth over the whole C band (i.e., 1530~1565 nm). The 3 dB gain bandwidth was improved to 21 nm. At a signal wavelength of 1550 nm, the maximum gain of all signal modes was up to 30.1 dB. Differential modal gain was maintained below approximately 1.3 dB.

“…With this, it still requires the use of good mathematical methods such as the variational method, functional analysis, supers metric approach, Nikiforov-Uvarov (NU, the asymptotic iteration method and so on In recent period, work has been carried out on to study bound state of KGE for a number of special potentials [1,15] even in the case of equal vector and scalar potential [16], because it reduces KGE to a Schrodinger type of equation which could in turn be transformed into hypergeometric differential equation that has a known solution using [17][18][19][20] and this is more reason why KGE is receiving attention considerably in the literature when it comes to use of potentials [21,22]. In fact it has been shown that exact solution are possible with some certain central potentials [23][24][25][26] which has help in investigation of bound states of the KGE for that particular potential which on the other hand has invariably led to derivation of the exact expression of the energy eigenvalues and the corresponding normalized eigenfunctionns in terms of some special polynomials and hypergeometrical function [16,[27][28][29].…”

In this work, we present the analysis of behavioral trend of Klein-Gordon Equation involving potential as regards when it comes to the study of particle, it has been observed that in every case of handling of KGE with potential of any type, it is made clear here that the equation has to first off all be transformed into a particular standard differential equation with a well-known solution which appears in form of implicitly defined transcendental equation. The equation on the other hand is to be solved analytically since the exact solution is not easily attainable without the use of mathematical tool especially when it comes to the consideration of the energy eigenvalue and the corresponding wave function because the solution is also always accompanied with a normalization constant often coupled with a condition that requires an arbitrarily chosen quantum number that come up when (l=0) and so on. In general, the analysis reveals the fact that the of trend of KGE involving potential gives a good understanding in the study of inter-molecular structure, diatomic crystals, and such case that involves inter-atomic interaction which is gives very nice idea in the study of bound state in atom.

“…Research on fiber lasers (FLs) is an area of growing interest in the last years, due to the high performance of these light sources. Multiple possibilities have been investigated, as high power CW FLs [1], pulsed FLs [2], multiwavelength FLs [3], and wavelength tunable FLs [4]. A particular kind are single-frequency FLs, characterized by a very narrow linewidth, which make them suitable for a wide range of applications in optical telecommunications such as wavelength division multiplexed optical systems, sensing, spectroscopy and interferometry.…”

Enhanced Q-switched distributed feedback fiber laser based on acoustic pulses

An acoustically Q-switched distributed feedback fiber laser with enhanced performance is presented. It is based on an FBG written in an erbium doped fiber, in which a dynamic defect is introduced by means of a short acoustic pulse. The performance of the laser depends on the reflectivity of the grating. In this work, we present two different Q-switched distributed feedback fiber lasers realized with active gratings of different reflectivities. Both lasers are characterized at different pump powers and repetition rates. It is shown that the performance of the laser based on the weaker grating was significantly improved with respect to the laser based on the stronger grating. In terms of peak power, the improvement was a factor of two. The average power was also improved. For example, at 50 kHz, it was increased from 280 μW up to 500 μW. In addition, we studied the performance of the laser when an electric square signal was used to drive the transducer, obtaining similar results to the case when a harmonic electric pulse was used.
