Paper Abstract

The fast development of laser technology requires creating a specialistic resource base for laser production certification together with radiant power (energy) measuring devices [1, 2]. This need becomes of special importance at the time when commencement of laser production at quantum points, holes and wires, whose dynamic scope of power and energy starts from counting individual photons up to tens of kilowatts (kilojoules), and the spectrum from ultraviolet to a near infrared [3]. Such are the characteristics of currently accessible laser radiation sources, used both for laser position finding and in other spheres of laser construction. Scattered radiation receivers, which are used in conditions of registering extremely low levels of radiant power, require examining of their metrological characteristics in order to define the value of their uncertainty. Elaborating such a laser set will constitute a basis for further improvement of a system for securing uniformity of measurements of basic energy parameters, characteristic for laser radiation. A set of standards now under elaboration will allow for the certification of all kinds of lasers. Choosing the optimum scheme for the elaboration of a new standard would enable the creation of a standard encompassing: a complete relation to ISO 11554- 2008 norms; with high accuracy of reproducibility of the volume of power unit (relative expanded uncertainty ~0,02%) and transmitting its volume; with an expanded power range P=1,0•10-2÷2,0[W] and with an expanded spectrum range λ=0,3÷10,6[μm]; with repeatability of measurements' results.
