Towards an ultrafast laser inscribed astronomical nulling interferometer in the mid-infrared

Abstract

One of the biggest challenges in modem Astronomy is the direct detection of extrasolar planets using ground based telescopes. While the small angular separation of the star-planet system is an unchangeable limitation, the contrast ratio can dramatically be improved by shifting the observing wavelength to the mid-infrared. In the astronomical L'-band (3.5–4… (More)
