    The exploitation of nonlinear effects in multi-layer thin films allows for optics with novel functions, such as all-optical switching and frequency conversion. In this contribution, an improved interferometric setup for ...
  • Paschel, S.; Balasa, I.; Jensen, L.O.; Cheng, X.; Wang, Z.; Ristau, D. (Bellingham : SPIE, 2018)
    Previous studies have shown that nanometer scale defects can lead to the formation of submicrometer craters, if located in coatings with a relatively small thickness. Due to the small size, such damages are challenging to ...
