Paper Abstract

We will use InGaAs and Ge based reflection type trap detectors as a detecting element and lasers as light sources to realize the absolute power and responsivity scales in the near infrared region. The output of lasers should be stabilized in order to make measurements on the metrological level. Therefore, we have established a home made laser intensity stabilization optics in the laboratory. The intensity stability of infrared lasers was reached to a level of 5x10-5 with this system. We have employed a spatial filter, which consists of a 10X objective, a 25 μm pinhole and a Plano convex lens in order to generate a clean beam with the desired dimension Circular power distributions and Gaussian properties of the beams were analysed by using a CCD beam profiler.
