Paper Abstract

Many laser systems use several laser beams which may interact either coherently or incoherently. Most physical optics codes model the propagation of a single laser beam. Some codes can analyze the kinetics of multiple laser lines. A powerful computer code, called LOTS2, has been developed at the Los Alamos National Laboratory by UNM which allows the simultaneous treatment of different laser beam trains. These beams may have different wavelengths, apertures, divergences, substantially different Fresnel numbers, and need not be colinear. Multiphoton phenomena such as Raman processes and isotope separation may be studied as well as conventional single photon phenomena. LOTS2 has a virtual memory feature that allows computer arrays to be larger than the central memory of mainframe machines such as the CDC 7600 and Cray 1. The separability of the diffraction propagation mathematics has been exploited to allow cylindrical lenses and high aspect ratio beam cross sections to be modeled. Considerable effort has been devoted to making the code easy to use.
