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...
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...
Harmonic operation of high gain harmonic generation free electron laser
harmonic operation HGHG FEL
2009/8/14
In high gain harmonic generation (HGHG) free electron laser (FEL), with the right choice of parameters of the modulator undulator, the dispersive section and the seed laser, one may make the spatial b...
