Laser monitor for remote object visualization

Abstract

The possibility of the visualization of remote objects using active optical systems with a copper vapor brightness amplifier has been investigated. Theoretical and experimental dependences for the field of view of the active optical system on the distance between the object and the brightness amplifier (laser monitor, laser projection microscope) have been studied. The visualization results suggest that as the object is moved farther from the brightness amplifier the field of view decreases and the quality of the obtained images gets worse. The maximum distance between the object and the brightness amplifier which is determined based on the superradiance pulse duration does not coincide with the visualization results. The field of view decreases as the distance between the object and the brightness amplifier increases. The feasibility of using a bistatic system for distant objects visualization has been shown.

Kinetics of the CuBr vapor active medium under non-typical excitation conditions

“…Note the high population inversion duration is of primary interest for visualization of processes from a long distance using the monostatic scheme of a active optical system when the single active medium operates as both the amplifier and the illumination source [19]. In this case, the active medium operates without a cavity and the illumination of the visualization object is performed by the amplified spontaneous emission (ASE).…”

Design of a metal vapor laser power supply

“…The most promising, in our opinion, is the use of lasers for precision micromachining of metals [1], visualization of high-speed processes including active optical systems based on brightness amplifiers on different metals vapors [2][3][4].…”
