Presenting Virtual Nonlinear Optics Workbook (vNOW). The software enables students and scientists to perform numerical experiments in nonlinear optics of two- or multi-level 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.
