We discuss the enhancement of transient stimulated Raman scattering from a pulse train due to molecular memory effects for atmospheric propagation. For horizontal propagation, we show that enhancement is negligible when the interpulse spacing in the

We present new pendulum-type equations for the propagation of two nonoverlapping pulses in a model swept-gain three-level amplifier. The predictions of these equations are compared numerically with corresponding predictions of the two-level Burnham

Some of the adaptive optics systems contemplated to ameliorate the effects of the atmospheric turbulence utilize guide stars. Guide stars are artificial beacons formed in the atmosphere by the interaction of a laser with matter in the atmosphere. Sod

The analysis of the performance of a binary optical element requires a physical optics calculation because of the diffractive nature of such elements. We have developed a number of software tools for this analysis, which are based on the Kirchhoff-Fr

A micro-optical element that is a combination of a phase diffraction grating and a convex lens will disperse and focus light of different wavelengths that fall on it. Such a device can be fabricated using binary optics technology to create a multilev

We undertake a theoretical investigation of the coherent optical propagation of Stokes light in a collisionally broadened three-level Raman amplifier. The Stokes light consists of two distinct spectral components: off-resonance stimulated Raman scatt
