Enabling rotary atomic layer deposition for optical applications.
Kochanneck L, Rönn J, Tewes A, Hoffmann GA, Virtanen S, Maydannik P, Sneck S, Wienke A, Ristau D. Kochanneck L, et al. Appl Opt. 2023 Apr 20;62(12):3112-3117. doi: 10.1364/AO.477448. Appl Opt. 2023. PMID: 37133158
In this work, the performance of a novel rotary ALD coating tool for optical applications is investigated and characterized with S i O (2) and T a (2) O (5) layers. Low absorption levels of <3.1p p m and <6.0p p m are demonstrated at 1064 nm for around 186.2 n …

[Studies on the magneto-optical rotation of porphyrins, hemins and methemoglobin compounds].
Rein H, Ruckpaul K, Ristau O, Haberditzl W. Rein H, et al. Acta Biol Med Ger. 1975;34(3):325-44. Acta Biol Med Ger. 1975. PMID: 1189812 German.
With iron porphyrins (hemin, heme and their complexes) the charge of the iron and the nature of axial ligands determine the position and intensity of the O-bands in the MOR spectrum. Low-spin complexes have a higher symmetry than the high-spin complexes. ...

Role of two-photon absorption in Ta2O5 thin films in nanosecond laser-induced damage.
Jensen L, Mende M, Schrameyer S, Jupé M, Ristau D. Jensen L, et al. Opt Lett. 2012 Oct 15;37(20):4329-31. doi: 10.1364/OL.37.004329. Opt Lett. 2012. PMID: 23073452
In this Letter we report on evidence that two-photon absorption also significantly triggers laser-induced damage in Ta(2)O(5) thin films at 532 nm and 8 ns pulse duration. For experimental verification, single layers of Ta(2)O(5)/SiO(2) mixtures have been analyzed.. …
