2011 Cavity Enhanced Spectroscopy
User Meeting and Summer School
June 26-29, 2011
Kingston, ON, Canada
The Advance Registration Deadline is March 31st, 2010.
The 2011 User Meeting and Summer School in Cavity Enhanced Spectroscopy (June 27th - 29th, 2011) is held at Queen's University in Kingston, Canada.
Newcomers to the field and those who are curious about the capabilities of cavity enhanced spectroscopy may also be interested in attending the one-day summer school at no extra cost. The summer school precedes the meeting and takes place in the same location on Sunday, June 26th, 2011.
The advance registration (Can$400 for regular participants and $200 for students) closes on April 30th.
Regular registration (Can$ 500/$300) is open until June 28th.
The abstract deadline has already passed, but if you only now decided to participate, please let us know and we will accommodate your contribution!

James J. O'Brien
Dr. O'Brien received his B.Sc. (Hons) from James Cook University, and his Ph.D. degree from the Australian National University. He joined UM-St. Louis after postdoctoral positions at the University of California-Berkeley, the National Research Council of Canada, and the University of Arizona.
Jim O払rien is an experimental physical chemist who specializes in fundamental and applied, high-resolution laser spectroscopy and gas phase analytical chemistry. The primary tool employed is Intracavity Laser Spectroscopy. ILS techniques provide tremendously enhanced sensitivity for obtaining quantitative absorption spectra. Research areas include: (1) the acquisition of quantitative absorption spectroscopy parameters (e.g., absorption coefficients for methane in the visible to near-IR spectral region to assist in interpreting spectra of the outer planets such as Neptune and line positions for the high-resolution spectrum of molecular O2 for visible and near-IR bands; (2) high-resolution electronic spectroscopy of small molecules (e.g., CuCl, NiCl, NiH) with a view to locating excited electronic states in these species; (3) the gas phase chemistries and species involved in a variety of chemical vapor deposition (CVD) processes (e.g., the plasma deposition of films of diamond-like carbon (DLC), diamond-like nanocomposites (DLN), and silicon oxide); and (4) the further development of the intracavity laser spectroscopy (ILS) technique for analytical purposes (e.g., in acquiring spectra at ultra-high spectral resolution) and its range of applications (e.g., extension of ILS into the IR region by use of fiber lasers).

Del Mar Photonics featured optical components
Del Mar Photonics continuously expands its optical components portfolio. Browse our online store, read monthly notes about our featured optical products or just send us your requirements or product ideas.
Axicon lens also known as conical lens or rotationally symmetric prism is widely used in different scientific research and application. Axicon can be used to convert a parallel laser beam into a ring, to create a non diffractive Bessel beam or to focus a parallel beam into long focus depth.
Del Mar Photonics supplies axicons with cone angles range from 130?to 179.5?for use with virtually any laser radiation. We manufacture and supply axicons made from BK7 glass, fused silica and other materials.

Rutile (TiO2) coupling
Del Mar Photonics offers optical elements made of high quality synthetically grown Rutile Titanium Dioxide crystals. Rutile抯 strong birefringency, wide transmission range and good mechanical properties make it suitable for fabrication of polarizing cubes, prisms and optical isolators. Boules having high optical transmission and homogeneity are grown by proprietary method. Typical boules have 10 - 15 mm in dia. and up to 25 mm length. Optical elements sizes - from 2 x 2 x 1 mm to 12.7 x 12.7 x 12.7 mm. Laser grade polish quality is available for finished elements. So far we the largest elements that we manufactured are 12 x15 x 5 mm, in which optical axis is parallel to 15 mm edge, 5 mm is along beam path, 12 x 15 mm faces polished 20/10 S/D, one wave flatness, parallelism < 3 arc.min. (better specs. available on request).

Manufacturing challenging optical components
Our group works to characterize the interaction of biomolecules with solid surfaces, writes Dennis Hore of University of Victoria, Canada. Nature designs proteins with well-defined structures in solution. The conformation of these molecules may serve a structural purpose, or a chemical one in the case of enzymes. In order to further the progress of technologies that immobilize such molecules on synthetic surfaces (like biosensors employing enzymes), it is important to have a detailed understanding and control of the interactions of these molecules with the surface more
For that project Del Mar has been able to manufacture all shapes of prisms from CaF2, fused silica, and ZnSe according to our custom specifications.
Del Mar Photonics online store features windows, prisms, lenses, attenuators, etalons, crystals and wafers, and other items.
