“…The brief results of the experimental verification of the algorithm performance with a full-scale optical scheme of the designed laser system are shown in the table 1. The experimental data was obtained with a repetitively pulsed CO 2 laser and a laboratory atmospheric range of 220-m long [2]. But in the experiments, the phase conjugate mirror of the laser amplifier was substituted with a corner reflector.…”

“…To determine limitations of the bright speckle algorithm in the distance range, we consider the amplitudes of two neighbor speckles in the plane of a receiver, assuming that the amplitude difference have to be about 20 % as it was realized in the experiments by [2]. For the mean statistical distribution of the received intensity in Far field, the latter means that…”

“…The results of testing the algorithm performance in a full-scale optical scheme with a repetitively pulsed CO 2 laser operating at the indoor atmospheric conditions are presented in [2]. The test experiments show that the algorithm allows one to increase a probability of hitting the receiver by the brightest speckle of the operation beam and to gain total laser energy delivered onto the receiver in the burst of pulses.…”

The principal phenomena limiting an accuracy of laser beaming of remote objects in atmosphere is the atmospheric turbulence that induces the laser beam wandering over the object. Recently, a novel algorithm, which is referred as "a bright speckle algorithm", was proposed to compensate for wandering of a repetitively pulsed laser beam, propagating along at the atmosphere range. In the paper we consider the restrictions on the algorithm performance, which are imposed by the atmospheric turbulence. The restrictions are imposed on a distance range of the algorithm as well as on coincidence accuracy of the probe and operation beam wavefront profiles, which are used for the algorithm realization.

A compact laser beam direction stabilization scheme is developed that provides the angular stability of better than 50 μrad over a wide range of frequencies from 800 to 4000 cm-1. The schematic is fully automated and features a single MCT quadrant detector. The schematic was tested to stabilize directions of the two IR beams used for dual-frequency two-dimensional infrared (2DIR) measurements and showed excellent results: automatic tuning of the beam direction allowed achieving the alignment quality within 10% of the optimal alignment obtained manually. The schematic can be easily implemented to any nonlinear spectroscopic measurements in the mid-IR spectral region.
