Postdoctoral Positions relevant to Del Mar Photonics
From time to time Del Mar Photonics posts announcements for PhD research scholarships and postdoctoral positions in different locations worldwide. Most of those positions are relevant to Del Mar Photonics product portfolio, so we belive that our current and potential customers can be intersted in those opportunities. To find more opportunities go to the main page and search for Postdoc on that page. Some positions can be already filled out - we do not track if the positions are current.
Laboratory of Molecular Fluid Dynamics
Instituto de Estructura de la Materia CSIC
Serrano 121, 28006 Madrid (Spain)
One post-Doctoral contract (1 + 1 years) is available in the framework of the Research Project "Molecular Astrophysics: The Herschel and ALMA Era"(CSD2009-00038) of the Spanish Ministerio de Ciencia e Innovacio'n. The successful candidate will be involved in a study of collisions of several molecular species of astrophysical interest, aimed at determining the rate coefficients for inelastic collisions at low temperature, and the formation of small clusters.
The tasks to be undertaken include: 1) laboratory spectroscopic measurements (by Raman spectroscopy with high time-space resolution) in supersonic jets of H2O or CO, and their mixtures with H2 and He; 2) data reduction to fluid dynamic quantities (densities, temperatures, rotational populations, flow velocities, etc); and 3) interpretation of the experimental data in terms of molecular collisions at the lowest temperature as possible.
The required instrumentation (high power lasers, grating spectrograph, expansion chamber and nozzles, high vacuum pumps) is fully operative at the laboratory. The sucessful candidate must have experience in molecular spectroscopy, and will be trained according to his/her background in Physics, Chemical-, Molecular-, or Statistical Physics, and Quantum Mechanics.
Well qualified candidates are invited to apply to the contact information below, including a CV and potential references.

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. Axicons, barium fluoride windows, germanium etalons, rutile (TiO2) prisms, microchannel plates and detectors, saturable absorber mirrors, photoconductive THz antennas, lithium niobate wafers and crystals and many other high quality affordable components for scientific research and OEM production are delivered globally from stock.
