چکیده

A laboratory experiment has demonstrated the effectiveness of compensating for forced-convection-dominated CW thermal blooming by using a deformable mirror to add phase corrections to the laser beam. In agreement with theoretical predictions, the peak focal-plane irradiance has been increased by a factor of 3 under severely bloomed conditions.

Thermal-Blooming Laboratory Experiments

• We conducted a multiphase series of laboratory experiments to explore the adaptive optics compensation of a laser beam distorted by strong thermal blooming. Our experimental approach was to create on a small, low-power beam the same phase distortion that would be experienced by a large, high-power beam propagating through the atmosphere and to apply phase compensation via deformable mirrors. ...

Correction for thermal distortions of laser beams with a flexible mirror. Experimental and numerical investigations

A mathematical model of an adaptive optics system was described in the article. The model included two main components: the model of an adaptive mirror and model of beam propagation under conditions of thermal blooming. Results of numerical simulation of adaptive optics systems were compared with data of laboratory experiments. High reliability of the model was shown.

Scaled Atmospheric Blooming Experiments (SABLE)

II The SABLE field experiments investigated the use of phase-conjugate adaptive optics to compensate for strong thermal blooming and turbulence. The experiments, conducted at the TRW Capistrano Test Site in southern California over horizontal paths of 100 and 400 m, were designed to explore issues related to the propagation ofhigh-power lasers from the ground to space. The laser used in the exp...
