Abstract:

Ruling Out Multi-Order Interference in Quantum Mechanics

Quantum mechanics and gravitation are two pillars of modern physics. Despite their success in describing the physical world around us, they seem to be incompatible theories. There are suggestions that one of these theories must be generalized to achieve unification. For example, Born’s rule—one of the axioms of quantum mechanics—could be violated. Born’s rule predicts that quantum interference, as shown by a double-slit diffraction experiment, occurs from pairs of paths. A generalized version of quantum mechanics might allow multipath (i.e., higher-order) interference, thus leading to a deviation from the theory. We performed a three-slit experiment with photons and bounded the magnitude of three-path interference to less than 10^–2 of the expected two-path interference, thus ruling out third- and higher-order interference and providing a bound on the accuracy of Born’s rule. Our experiment is consistent with the postulate both in semiclassical and quantum regimes.

Tighter Tolerances for Flow Control Components

At an ever increasing rate industry is requiring tighter tolerances on flow control components.  As a supplier of laser drilled orifices in a variety of components, Lenox Laser, Inc. has been meeting these tighter tolerance requirements for several years.  Incidentally, these very tight toleranced parts have been in high demand.  To accommodate this demand, Lenox Laser has developed proprietary processes that allow tolerances to be consistently held.  Tolerances can be as tight as +/-0.5% and +/-1% on a 10 micron or larger hole sizes.  Compare this to standard tolerances that typically range from +/-5% and larger with respect to the hole size (i.e. a 1 micron hole can have a standard tolerance of close to +/-50% depending upon the part material and thickness).  Often customers may need not just tighter tolerances on a nominal size but matched sets or pairs with tolerances of +/-1-2% of each other.  Integration of the laser process with its flow testing capabilities ensures repeatable results with higher yields.  Very tight tolerances can be held on most standard flow components we offer, as well as, customer supplied parts.  Visit our website at www.lenoxlaser.com or email sales@lenoxlaser.com for more information.

Microlensing

The Lenox Laser Corporation of Glen Arm, MD, hosted a seminar that featured a wide range of topics in the field of light and optics. One of the topics of great interest was "microlensing". Go to the following web address for a great article about this very intriguing subject.

Lenox Laser Nondestructive Micromarking and Microimaging Technology

The Lenox Laser Corporation of Glen Arm, Maryland, has recently developed an advanced laser supported technology that can produce nondestructive marks and images with submicron resolution on most materials. If you are concerned about accessibility, traceability, security, encryption, archiving, and risk management, then you may wish to contact Greg Solyar, senior scientist, for more information by calling 410-592-3106 (1-800-494-6537) or by sending an email to engineering@lenoxlaser.com

Do You Need Microleaks in Food or Drug Packaging?

The Lenox Laser Corporation of Glen Arm, Maryland, has mastered several processes unique to the food, drug and pharmaceutical industries. Lenox Laser has created traceable flow rate validation techniques in a wide range of materials and products including bags, cans, bottles, vials, ampoules, etc. We feature both short and long run leak testing processes. For more information, call Bob Gidner, senior flow engineer, at 410-592-3106 or email engineering@lenoxlaser.com

Metrology Automatic Measuring

Lenox Laser has recently purchased a smartscope FLASH metrology system.
The machine will automatically measure down to a three micron aperture.
We also offer quality reports as an additional service.
Optical Gauging Products,Inc, is one of the leaders in field of metrology.
Our Smartscope Flash 200 Video Inspection System is a great asset to our quality assurance program.

PicoLaser Drilled Nanometer Holes for the Semiconductor Industry

Lenox Laser is introducing a series of flow calibrated nanometer holes to the semiconductor industry in tungsten, 304 stainless, nickel; gaskets and fittings. The process of picosecond laser drilling is a recent development with new solid state UV lasers. Lenox Laser has designed systems for the purpose of drilling cleaner and smaller holes with closer tolerances. This process has also given us the ability to generate more precise micro flow rates with tolerances that have exceeded our expectations.

Process Development

The personal goal and commitment of each member of the Lenox Laser Corporation’s engineering team is to provide each customer with reliable and robust products made to specified custom requirements and conditions, such as, high energy light beam densities, aggressive chemical and biological environments, mechanical stresses and vibrations, aerospace and underwater uses, etc.
We have a wide range of tools at our disposal. Our lasers range from CW to picoseconds in pulse widths; from far IR to hard UV wavelengths; from Joules to micro-Joules in laser beam energy. We can drill to a specified gas or liquid flow or light intensity. We have a fully equipped machine shop and chemical etching capabilities. Our experienced staff can combine some or all of those capabilities in a multi-step process where a single technique application becomes impractical or impossible. In each unique case, the choice of product materials and manufacturing processes are specific and may affect future product performance.
Both our production and engineering teams are readily available to help customers to consider those specifics in the original product design. We may suggest developing and redesigning a product to create both a feasible and cost effective project.
Lenox Laser has a distinguished history of successful medical product development under the auspices of NIH grants enabling us to introduce innovative products to a highly competitive global market. We have pioneered and have become an industry standard in a metrology associated with holes drilled for leak detection in the medical, pharmaceutical, automobile and food industries.

High Energy Aperture Holder (MT-1, MT-1R)

Spatial filtering of a high energy laser beam is not a trivial problem when the energy density of the focused beam approaches the ablation threshold of the optical aperture material.
Materials with a high ablation threshold have very low thermal conductivity; thus, depending upon the repetition rate of laser pulses, can become subject to melting proceeded by aperture damage.
The Lenox Laser Corporation has developed the MT-1R high energy aperture holder that uses the combination of reflecting and heat dissipating parts to reduce by a few orders of magnitude the energy density that reaches the aperture. This method significantly extends the lifetime of the optical aperture. The MT-1R dimensions were selected in order to fit most of the optomechanical mounts designed for one inch mirrors or lenses provided by leading manufacturers, namely CVI-Melles Griot, Newport, New Focus, Thorlabs, Edmund Optics, etc.
When MT-1R is mounted in one of the above mentioned mounts it becomes an integrative part of the existing optical layout or device and does not require any additional adaptors.
