The unstabilized laser source is represented by compact planar waveguide external cavity laser module, ORIONTM (Redfern Integrated Optics, Inc.), working at 1540.57 nm with a 1.5-kHz linewidth. We built up the unbalanced Michelson …
Zerodur has both an amorphous (vitreous) component and a crystalline component. Its most important properties are: • Particularly low thermal expansion: in the range 0 to 50 °C it has a mean of 0 ± 0.007×10 K , which is two orders of magnitude better than that of fused quartz. • High 3D homogeneity with few inclusions, bubbles and internal stria (as contrasted to Cer-Vit). painful lump in calf of legWebN-BK7 is a Schott designation for the most common Borosilicate Crown glass used for a wide variety of visible applications.
