Presenting
Virtual Nonlinear Optics Workbook (vNOW). The
software enables students and scientists to perform numerical experiments in
nonlinear optics of two or multilevel atoms, and
includes two dozen samples
with study problems. A
free
demo.
We hope you
will enjoy using vNOW. With vNOW
you will get your first result by pushing a single button. In the default
simulation, a laser pulse is exactly tuned to an atomic transition. How does the
picture change if the laser is tuned off? What is the effect of relaxation or
spectral inhomogeneity? Just change the parameters and you will see. Step by
step, the virtual experiment develops and so does your understanding of the
phenomenon in hand. Alternatively, you may bring vNOW into play by opening a
sample.
The
cornerstone of vNOW is an optimized code for computing the evolution of
the density matrix of multilevel atoms. Monte Carlo method is included to
calculate timedomain responses of a spectrally inhomogeneous ensemble of atoms.
For each transition in a two, three or fourlevel atom you define its
wavelength, and population and coherence decay times. For an arbitrary number of
laser pulses with up to two frequency components, each of them interacting with
a specified atomic transition, you may enter the values of amplitude, phase and
detuning. The output is in the terms of the density matrix elements, i.e. in the
terms of the population of energy levels and the coherence between a pair of
levels. Simple dialogs and commands enable you to view results and generate
student reports. The study problems help to learn more about the sample
simulations.
If you are
interested in the dynamics of two or multilevel atoms, their relaxation and
interaction with light, the basics or hot topics of quantum interference – try
vNOW!
