“…In this case, the un pumped region of the fiber absorbs the signal thus, resulting loss in signal rather than gain in that section. Figure (4) shows the gain coefficient as a function of the input power for different values of fiber length. This figure shows that for fiber length L=10m the gain reaches a saturation level.…”

A theoretical study for three level laser systems, describes the interaction process between optical fields and optical fiber material of amplifier. This study gives a simple approach expression for gain coefficient which depends on some parameters such as input power pump rate, number of doped atoms per unit volume, fiber length and core radius. It has been found that In order to keep the fiber amplifiers doped with praseodymium as short as possible with good efficiency, it is best to increasing the doped concentration. For 3m length and 3 24 ion/m 10 5 24 ion/m 10 8 .

“…AV Smith et al [9] provided a numerical demonstration of the population inversion saturation and stimulated thermal Rayleigh amplification associated with laser amplification of a large-mode fiber amplifier. Chen Peiying et al (2012) [10] suggested a numerical Euler method solution to the fiber optimizer's frequency equation's initial value problem. Because of the unique properties and possible advantages of active fibers, heavily doped phosphate fibers were used [11].…”

In the optical (380-700 nm) region, a simulation study was conducted to assess the low-signal gain, power conversion efficiency (PCE), and optical output power of a praseodymium-doped fiber optic amplifier (PDFA). The PDFA performance was assessed using the optimized Pr3+ fiber length, Pr3+ ion concentration, and pump power. Additionally, the effects of input signal voltage and amplifier gain on amplified spontaneous emission (ASE) were investigated. A lower peak signal of roughly 1 dB at 635 nm was obtained with a shorter 5 m Pr3 + doped fiber and a higher pump power of 300 mW. The impact of wavelength and pump power variations on the amplifier's optical output power's spontaneous enhanced emission (EEM) is examined. Finally, the ionic interaction (general-purpose conversion effect) in the low-power amplifier signal is analyzed by taking into account various values of the upconversion factor. Keywords: Praseodymium doped fibre amplifier, Small-signal gain, Pump power, Ultrashort laser.

This paper is based on the numerical solution of the rate equations model and their gain dependences are discussed. Simulation of the amplifier gain versus the pump power, amplifier length, ion concentration and core radius has been done. In order to keep the fiber amplifiers doped with ytterbium as short as possible with high gain, it is best to increase the doped concentration. For 10m amplifier length, pump power of 25mW, core radius of 2.5m and 3 ion/m 25 10 3.5 doping concentration, the gain is 60dB. Increasing of the core radius would increase the threshold pump power and at the above same conditions, the optimum gain is at 5m core radius.
