Current state of laserometry and prospects of its development as a measurement field

摘要

The principles and the status of a system for assurance of measurement uniformity in laserometry are outlined and the functions of VNIIOPI as the National Scientific Metrology Center responsible for assurance of measurement uniformity are described. The tasks of laserometry as applied to the needs of economics have been stated. The basic trends in laserometry development for the next decade have been designated. It has been shown that first of all it is necessary to master: ultraviolet and x-rays ranges of the spectrum; ranges of ultra-low (less than 1 x 10~(-10)) intensity values and super-high (more than 10~5) power and energy values; narrow-aperture (micrometers) and broad-aperture (tens of centimeters and greater) laser beams; ranges of ultra-short (subpico- and femtosecond) laser radiation pulses, especially in UV and x-rays ranges of the spectrum.
