Abstract:
Abstract The problem of small bit error rate is actual in fiber Raman amplifiers. Our experimental data on the amplified spontaneous emission (ASE) with backward pumping as a base of optical noise evaluation are presented in this paper. Raman gain spectrum for useful Stokes low-powered signal is calculated and compared with obtained spectrum of non-coherent ASE noise. It is shown that output optical signal has better gain than the amplified spontaneous emission that leads to appreciable growth of output optical signal-to-noise ratio.

AbstractThe minimum irradiance needed to overcome amplified spontaneous emission (ASE) of a seed beam injected into a laser amplifier is evaluated. The treatment is particularly applicable to extreme ultraviolet (EUV) and X-ray laser schemes to inject laser harmonic radiation as a seed into (1) plasma laser amplifiers and (2) free-electron lasers. Simple expressions and calculations are given for the minimum injected irradiance required for amplification of the injected seed beam to exceed ASE from the amplifier, including the effects of gain saturation, assuming one dimensional radiative tran

Abstract:
Abstract In this paper, the effects of pump pulse fluence on the output energy and amplified spontaneous emission (ASE) of a femtosecond regenerative amplifier are investigated. One can easily enhance the output energy of laser amplifiers by increasing their pump fluence. This in turn can increase the ASE and reduce the performance of amplifiers in terms of output beam quality, beam stability, etc. This effect would eventually lead to what is called ‘temporal intensity contrast deterioration’. In this work, it is shown that an optimum state of the pump pulse fluence can indeed optimize the amo

Abstract:
Reversible oxygen induced emission quenching of both the Spontaneous Emission (SE) and the Amplified Spontaneous Emission (ASE) of poly(9,9-dioctylfluorene) waveguides is demonstrated. We show that ASE shows a stronger quenching than SE, up to about 6.2 times, but also a stronger decrease when the excitation density increases. We conclude that the fast increase of the ASE decay rate is the main process in determining the ASE detection sensitivity, limiting the potentiality of sensitivity improvement of ASE with respect to SE.

AbstractIn order to achieve the truncated amplified spontaneous emission pulse, the method of timeshare quenching was proposed in this paper. When the original pulse of the amplified spontaneous emission is 16.72 ns, the obtained best results show that the pulse width is truncated to 2.48 ns, and the shortening ratio is approximately 6.7. By analyzing the 12 acquisition results of the continuous amplified spontaneous emission truncation, 2.59 ± 0.05 ns amplified spontaneous emission pulse was obtained. The experimental results showed that the stability of the truncated pulse width is well. Thi

Surface plasmon-polaritons are optical surface waves formed through the interaction of photons with free electrons at the surface of metals. They offer interesting applications in a broad range of scientific fields such as physics, chemistry, biology, and material science. However, many of such applications face limitations imposed by the high propagation losses of these waves at visible and near-infrared wavelengths, which result mainly from power dissipation in the metal. In principle, the propagation losses of surface plasmon-polaritons can be compensated through optical amplification. Th

Recently the time dependence of gain in a Ti:Al2O3 amplifier was measured.1 It was shown that the decay of gain was much more rapid than expected if only spontaneous decay was responsible for depletion of the upper state. Although it was believed that amplified spontaneous emission (ASE) might be responsible for this difference, the apparent difficulty of calculating the effect of ASE inhibited pursuit of this conjecture. A rate equation has been used to demonstrate that ASE can quantitatively explain the fast decay. In this model, the gain of the amplifier is e γ , where γ obeys the time-depe

However, the output beam of the four-pass amplifier involves quite big amplified spontaneous emission(ASE). They reported that the ASE portion reached to 15 % in normal operation.
