Abstract

The method of measureing laser power and wavelength at the same time using a hijunction silicon color sensitive cell as a detector is presented the performances of the instrumentwhich consists of detector

light current amplifier

A/D translator and computer are discussed. At first the wavelength is detected andethen the wavelength sensitivity of the detector is calibrated by the computer automatically during the laser measurement.The measuringerrors are within ?2.5% for light power and ?2.5nm metr for wavelength separately.
