Abstract:
A laser monitor system with independent brightness amplifier and a mirror scheme of image formation based on active copper bromide vapor medium is described that allows visualization of the surface of metal nanopowder during high-temperature combustion. Independent brightness amplification using second active element based on copper bromide vapor significantly increases the image contrast as compared to that in a laser monitor with single active element, which is advantageous for studying the surface of materials with low optical reflectance. In addition, it is demonstrated that a two-channel generator of pulses for pumping active elements on copper bromide vapor can be implemented on a single high-voltage power-supply source.
Keywords:
