Controllable steep dispersion with gain in a four-level N-scheme with four-wave mixing
Controllable steep dispersion gain four-level N-scheme four-wave mixing Atomic Physics
2012/5/31
We present a theoretical analysis of the propagation of light pulses through a medium of four-level atoms, with two strong pump fields and a weak signal field in an N-scheme arrangement. We show that ...
Generation of Bragg similaritons in nonlinear fiber Bragg gratings with gain
Generation of Bragg similaritons nonlinear fiber Bragg gratings gain Optics
2012/5/29
We have explored through numerical simulations the amplification of laser pulses in nonlinear fiber Bragg gratings with gain and normal dispersion. The distortion of the temporal intensity profile cau...
Nonlinear sigma model for optical media with linear absorption or gain
Nonlinear sigma model optical media linear absorption gain Optics
2012/4/24
In the framework of the Keldysh technique, we formulate the nonlinear sigma model for disordered optical media with linear absorption or gain. The effective action for fluctuations of the matrix field...
Unconventional modes in lasers with spatially varying gain and loss
lasers spatially varying gain and loss
2011/9/2
We discuss a class of lasing modes created by a spatially inhomogeneous gain pro le. These lasing modes are \extra modes", in addition to, and very di erent from, conventional lasing modes,which arise...
Monte-Carlo-based spectral gain analysis for THz quantum cascade lasers
THz quantum cascade lasers Monte-Carlo-based spectral gain analysis
2011/9/14
Employing an ensemble Monte Carlo transport simulation, we self-consistently analyze the spectral gain for different THz quantum cascade laser structures, considering bound-to-continuum as well as res...
Laser emission with excitonic gain in a ZnO planar microcavity
Zinc oxide microcavity strong coupling, VCSEL
2011/8/26
The lasing operation of a ZnO planar microcavity under optical pumping is demonstrated from T=80 K to 300 K. At the laser threshold, the cavity switches from the strong coupling to the weak coupling r...
Energy Phase Correlation and Pulse Dynamics in Short Bunch High Gain FELs
Energy Phase Correlation Pulse Dynamics in Short Bunch High Gain FELs
2010/11/16
We analyze the dynamics of Free Electron Laser (FEL) devices, operating with a bunched beam exhibiting a longitudinal phase space correlation. We show that the presence of an energy-position correlat...
Ginzburg-Landau equation for dynamical four-wave mixing in gain nonlinear media with relaxation
four-wave mixing Ginzburg-Landauequation Maxwell-Bloch system in optics
2010/4/7
We consider the dynamical degenerate four-wave mixing (FWM) model in a cubic nonlinear medium including both the time relaxation of the induced nonlinearity and the nonlocal coupling. The initial ten-...
