Optics for Space and High Energy Ions (GOLD-FOTION)

Group description:
Optics of Thin Films sub-line addresses the development of advanced coatings and measurement techniques to improve the efficiency of optical instruments and the knowledge of the optical properties of materials mainly in the far and the extreme ultraviolet. Study of the fundamental mechanisms of the electronic damage caused in crystals by high energy heavy ions, and of the modified optical properties of the irradiated materials for novel photonic applications.

Congresses and Conferences Thursday, April 25, scientific coffee with Juan Pedro Adrados 2024-04-11 The first scientific coffee this spring will be on April 25 with the talk “In vacuum through time (without black holes)” given by our colleague Juan Pedro Adrados Encinas from the GOLDION group at 11 a.m. in the meeting room. conferences, followed by a coffee at the club+terrace. News Formation of hollow silver nanoparticles under irradiation with ultrashort laser pulses 2024-03-20 We have studied the formation of cavities in spherical silver nanoparticles embedded in silica, irradiated with fs laser pulses that produce an intense electronic excitation. Congresses and Conferences Wednesday, January 25 scientific coffee with Paloma López Reyes 2024-01-12 This month's talk is from the Thin Film Optics Group. News Chemometric-driven quantification of construction and demolition waste using Raman spectroscopy and SWIR: Enhancing sustainability in the ceramic sector 2023-11-24 This cost-effective methodology allows for quantification of stone aggregates within construction and demolition waste, improving its recycling potential in the ceramic sector. Direct measurement of the extinction coefficient by differential transmittance 2023-11-22 A team of researchers from the “Daza de Valdés” Institute of Optics and the “Blas Cabrera” Institute of Physical Chemistry of the CSIC and NASA Goddard Space Center has developed an innovative procedure to precisely measure the extinction coefficient for sheets of very transparent materials. Correlation between structure and mechanical properties in α-quartz single crystal by nanoindentation, AFM and confocal Raman microscopy 2023-11-07 The study reveals the correlation between the internal structure and mechanical properties in the α-quartz single crystal. Unveiling the effects of the surface and in-depth nanostructure on the far-UV optical reflectance of thin fluoride multilayer coatings 2023-11-03 The published work studies a new optical coating that seeks to satisfy the necessary improvements in the detection of light in the far ultraviolet that future exploration missions such as the so-called “Habitable Worlds Observatory” need Far UV coatings for liquid-Ar time projection chambers 2023-09-22 This work presents coatings designed to enhance the optical properties of the detector materials and to be an alternative to the current technique. Congresses and Conferences Women from the Institute of Optics “Daza de Valdés” 2023-03-08 At the Institute of Optics " daza de Valdés" we wanted to make visible the women who work in the institute in a series of photos. Lecture by our colleague Juan Pedro Adrados on April 16 at MUNCYT 2023-03-01 Next April 16 at 12 noon within the conference cycle “Science in the first person”, we will be able to attend the conference entitled “The void, when nothing is important” that will be given by our colleague Juan Pedro Adrados responsible for Low Pressure Laboratory, belonging to the Madrid Community Laboratory Network.

News The INstituto de Óptica develops the transmittance filters used by the Chinese satellite FY-3E to predict the weather 2021-08-04 The Thin Film Optics Group from the Institute of Optics has manufactured the satellite filters that select the spectral bands in which meteorological data will be obtained Optimization of the deposition parameters of MgF2/LaF3 narrowband reflective FUV multilayers 2021-06-24 The study found a compromise deposition temperature of ~240° C and 13 bilayers for optimal reflectance. Above this deposition temperature, the stress increased, which resulted in an extension of the cracked area and a slight increase in roughness and decrease in reflectance in this light. Layers that were deposited at room temperature and then annealed resulted in reflectance and stress similar to that of coatings hot-laid for the same temperature. Graphite to diamond transition induced by photoelectric absorption of ultraviolet photons 2021-02-25 At present, two basic processes have been successfully tested to drive this transition: hard strokes and high-energy femtolaser excitation. They induce it by increasing the pressure or temperature in the graphite. In this work we present a third method that consists of the irradiation of graphite with ultraviolet photons of energies greater than 4.4 eV. Mirrors for Space Telescopes: Degradation Problems 2020-12-02 In addition to the deterioration produced by these environments, it is very difficult, usually impossible, to repair these mirrors once they have deteriorated. Why does the Adachi procedure work to avoid divergence in optical models? 2020-10-16 The article rigorously demonstrates the Adachi procedure. It also establishes the conditions to be able to apply this procedure. Finally, it is shown that the Adachi procedure is equivalent to a convolution procedure of the optical constants with Lorentz oscillators that the same authors had developed in 2018.
