NSF Center for Coatings Research

November 6-7, 2017 | Stanford University


CMS Co-Founder Garrett Cole attended the kick-off meeting for the newly launched LIGO Scientific Collaboration (LSC) Center for Coatings Research (CCR), held during the first week of November at Stanford University. Funded by the National Science Foundation (NSF) and the Gordon and Betty Moore Foundation, the CCR seeks to extend the reach of next-generation gravitational wave detectors by addressing the dominant noise source limiting their performance, namely thermal noise in the interferometer end mirrors. This noise arises from dissipation processes driven by the thermal excitation of the vibrational modes of the optics and ultimately reduces the number of observable gravitational wave signals from astronomical sources. The CCR combines groups from across the United States working on computational modeling of amorphous materials, deposition of coatings, and characterization of their atomic structure and macroscopic properties. CMS, along with MLD Technologies and LMA, will participate as industrial partners, working with long-time collaborators including Prof. Gregg Harry‘s group from American University in Washington DC and Prof. Steven Penn‘s group at Hobart and William Smith Colleges, in Geneva, New York. The ten academic institutions that form the CCR are: American University; California State University, Los Angeles; California State University, Fullerton; Colorado State University; Hobart and William Smith Colleges; Stanford University; Syracuse University; University of California, Berkeley; University of Florida; and Whitman College.

Laser World of Photonics in Munich

Laser World of Photonics in Munich is always a highlight for the general photonics industry and especially for CMS. Once again, this year was no exception. For the 2017 edition of the conference and tradeshow, CMS presented two talks at CLEO/Europe-EQEC, was a contributor to another two talks, displayed our products and technology in our booth, and was selected as a top 5 finalist in this year’s PHOTONICS Award. After a very competitive pitching session, we were thrilled to have been selected as the third-place winner of the PHOTONICS Award as part of the Start-up World at the Laser World of Photonics. Winning this prize highlights the accomplishments of our young organization and increases the awareness of our products and technology in the competitive photonics sector. It is always enjoyable to receive confirmation on how our work is redefining the field of precision laser optics.

We would also like to thank everyone who visited us and for the great discussions at our booth. We look forward to collaborating on new projects and solving challenging problems for our customers!

Christian Doppler Laboratory for mid-IR spectroscopy and semiconductor optics

We are very proud to announce that CMS is a co-sponsor of the newly launched Christian Doppler Laboratory (CDL) at the University of Vienna together with the bmwfw (Bundesministerium für Wissenschaft, Forschung und Wirtschaft) and the Christian Doppler Gesellschaft. Christian Doppler Laboratories are a unique example of how academia and industry can work together to develop commercial products from fundamental scientific research. The Christian Doppler Laboratory at the University of Vienna under the leadership of Dr. Oliver Heckl will focus on mid-IR spectroscopy and semiconductor optics.

Dr. Oliver Heckl was one of the first Crystalline Mirror Solutions (CMS) collaborators in 2013 when he was working at JILA in Boulder, Colorado. At CMS, we are extremely proud to collaborate with Dr. Heckl, particularly given his outstanding academic and industrial experience. We are very much looking forward to working even closer with Oliver and his exceptional research team. Being a spin-off from the University of Vienna with co-founder Prof. Markus Aspelmeyer, we are excited to remain in close collaboration with the university. The laboratory was officially opened on June 20, 2017 with a ceremony at the University of Vienna with participants from all four involved parties: the Christian Doppler Gesellschaft, bmwfw, the University of Vienna, and CMS. Dr. Garrett Cole, co-founder and CTO, made a video that was played at the ceremony in which he discussed the steps required to come this far and the challenge of finding the ideal candidate for this collaboration. Check out Garrett’s video below.

The research to be pursued at the CDL will cover all aspects of cavity-enhanced frequency comb spectroscopy, striving to extend frequency comb technology further into the mid-IR spectral region and pursue applications with these frequency combs in the fields of trace gas detection, precision spectroscopy, and molecular fingerprinting. Progress in the mid-IR spectral region has been hindered in large part by the lack of high-quality and low-loss optics. At the CDL, we will explore the advantages and possibilities of newly available high reflectivity and low-loss optics in the mid IR. These revolutionary mirrors will be based on semiconductor supermirror technology provided by CMS.

Please keep an eye out for future announcements arising from this exciting collaboration between the CDL and CMS.

Check out the latest article about CMS in the May edition of Electro Optics Magazine

Read the latest article about an exciting application of our crystalline coatings and their future in space. It was published in the May edition of Electro Optics magazine.

At the moment, our technology is still earth bound, but things might change in the course of the coming years. This article addresses the challenges of space-based optical coatings and their requirements for ultra-high quality mirrors.

CMS is currently working as part of a consortium led by Airbus and funded by the European Space Agency (ESA) on the implementation of crystalline coatings in space-relevant applications. The ultimate goal of this project is to supply a robust and high-performance optical reference cavity for the construction of a near-infrared “optical local oscillator”.
