Abstract

New instrument for measurements of laser pulse energy is described. Due to its parameters it can be used as a standard for unit of energy of pulse laser radiation. The instrument consists of a control unit, three sources of laser radiation, two receivers of optical signal, and a laptop. The whole system can be easily transported enabling one to carry out measurements in situ, at customer's, not only in laboratory conditions. This is a very important feature of the instrument because it allows inexpensive calibration and testing of large industrial laser installations and interesting laboratory intercomparisons as well. A method of measurement used in operation of the standard is presented. Main characteristics of the standard are shown. Methods of calculation of uncertainties of measurement during laser energy meters calibration by means of the standard of energy unit of pulse laser radiation are also presented. An alternative measurement option of the standard operating as an energy calibrator for unknown pulse optical radiation source is also available. Some results of testing of laser energy meters at eye-safe wavelength (1.54 micrometer) are presented.
