Optical multichannel recorder and its application in studying a picosecond dye laser

The authors created and applied an optical multichannel recorder with a PZS matrix detector for investigating the parameters of laser radiation. The instrument, called on OMR (optical multichannel recorder), records the spatial intensity distribution of a radiation pulse incident on the detector, memorizes it, reproduces it in the form of a semitone map on a television display, and outputs the signal intensity at any point, the intensity distribution over a given cross-section (line), and the integral over the cross section to a digital display.
