# Laser-interaction-in-fields-rate-equations-forces | ||
C++ code for laser interaction and forces | ||
|
||
Rate equations simulation of particles in fields | ||
|
||
All details are found in the USER GUIDE. Here is simply the most relevant part. Modifications (new versions) are in Modif_code.txt | ||
|
||
The program solves the rate equations to study laser excitation, forces (scattering + dipolar + magnetic + electric + coulombian | ||
interactions). | ||
|
||
|
||
It has been developed under Code::Blocks and Windows. The inputs are 2 external files describing the levels (with information about their energy + linear or quadratic Stark, Zeeman effect) and the transitions lines (dipole transitions, photodetachement or photoionization cross sections). | ||
|
||
A file named Liste Param.h contains parameters to run the simulation such as: | ||
sample size, temperature, magnetic fields and for the laser beams (waist size and position, polarisation, power, linewidth, wavelength, ...). | ||
|
||
A Kinetic Monte Carlo algorithm evolves in motion (forces under extranal fields + optical dipole forces) and event (absorption or emission) | ||
|
||
The output is writen in a file containing relevant information such as population in given levels and statistics about velocities (temperature), potential energy ... Output is also performed through 3D snapshots. | ||
