Laser Communication and Propagation through the Atmosphere and Oceans X.
In this work, a set of coupled equations is presented that describes the spot size and pulse length evolution of a Kerr focused ultra-short laser pulse in a turbulent and group velocity dispersive atmosphere. Solutions to the equations are compared a

Effective performance of laser systems intended for power delivery on a distant object requires an adaptive optics system to correct the laser beam distortions caused by atmospheric perturbations along the propagation path. The turbulence-induced eff

Corruption of the wavefront, beam wondering and power density degradation at the receiving end are the effects typically observed at laser beam propagation through turbulent atmosphere. Compensation of these effects can be achieved if the reciprocal

Effective performance of forthcoming laser systems capable of power delivery on a distant target requires an adaptive optics system to correct atmospheric perturbations on the laser beam. The turbulence-induced effects are responsible for beam wobbli

The requirements for obtaining cryogenic temperatures (i.e. 150 K and below) by anti-Stokes fluorescence cooling are analysed for a dielectric cooling medium located inside the cavity of a diode-pumped solid state laser. The cooling efficiency is der

Due to recent demonstrations of cooling by anti-Stokes fluorescence the optical geometries under which the cooling efficiency can be optimized are investigated. Since the cooling efficiency is proportional to the absorbed power of radiation, and in p

A viable beam control technique is critical for effective laser beam transmission through turbulent atmosphere. Most of the established approaches require information on the impact of perturbations on wavefront propagated waves. Such information can
