The client is an academic department conducting fundamental atomic physics research. The target of a Laser is a single Alkali atom, which enlarges to the size of several microns, upon receiving the pulse excitation. The enlarged atom is called a Rydberg atom and can reach the size of a grain of sand. The enlarged atom has new physical properties that are characterized by a detector that creates fast analog data streams. The setup of the experiment involves generating femtosecond Laser pulses, and capturing a 0 to 15 Volt ramp function with a very stable baseline voltage. It is very important to capture both the high voltage part and the near zero baseline part at the same time and with a resolution of 1 milliVolt in order to detect very small sub-atomic quantum chaos interactions. The signal pulse repetition frequency is 25 kiloHertz and 500 pulses should be captured at 50 MegaSamples per second during a 20 millisecond time period of interest. Products & Services
Mass spectrometers separate ions by their mass-to-charge (m/z) ratios. They are used to identify compounds by the mass of one or more elements in the compound. They are also used to determine the isotopic composition of one or more elements in a compound.
Atomic emission and optical emission spectrometers determine analyte concentration via a quantitative measurement of the optical emission from excited atoms.
Excimer lasers are rare-gas halide or rare-gas metal vapor lasers that produce relatively wide beams of ultraviolet laser light. They operate via the electronic transitions of molecules.
Laser marking equipment uses a high-powered laser to mark or scribe materials with text, images, patterns, and graduations.
Carbon occurs in a variety of forms such as vitreous carbon, pyrolytic graphite, hexagonal graphite and polycrystalline diamond (PCD). Carbon and graphite materials have high refractoriness while diamond has the highest hardness of all known materials.
