Plasma Physics and Controlled Fusion , 63 ISSN Brillouin amplification in plasma is more resilient to fluctuations in the laser and plasma parameters than Raman amplification, making it an attractive alternative to Raman amplification.

Through analytic theory and multi-dimensional particle-in-cell simulations, we identify a parameter regime for which Brillouin amplification can be efficient while maintaining filamentation of the probe at a controlled level. High pulse quality is maintained through control of parasitic filamentation, enabling operation at large beam diameters. Provided the pump and probe pulse diameters can be increased to 1 mm, our results suggest that Brillouin amplification can be used to produce sub-picosecond pulses of petawatt power.

Fiber optical parametric amplifiers FOPAs are an innovative type of amplifier with many promising applications both in and outside the telecommunications band. This severely limits the available pump power in fiber and thus the achievable FOPA gain. In this study we propose and demonstrate the effectiveness of using a chirped sinusoidal waveform to phase modulate the pumps and mitigate SBS. The effectiveness of the system for SBS suppression was confirmed by phase dithering a pump with the proposed chirp and measuring the increase in the SBS threshold. The system effect on the idler signal integrity was also measured following amplification from a two pump FOPA. Using the proposed systems, we successfully achieved as much as 38dB of conversion efficiency gain with an OSNR penalty of 0. Skip to main content.

Analytical approach of Brillouin amplification over threshold.


Posted on as a part of the Photonics Spotlight available as e-mail newsletter! Author: Dr. Abstract: It is discussed why in the context of modeling of fiber amplifiers and lasers it is normally reasonable to treat nonlinear effects only to a limited extent. I am often asked whether my fiber amplifier and laser modeling software RP Fiber Power can be used for modeling nonlinear effects. Strictly speaking, it can't, as it is not able to calculate the generation of power at new wavelengths through nonlinear effects, including the back-action depletion on the original wavelength components.
