It is well known that molecules exhibit molecular spectroscopic signatures in the mid-wave IR MWIR to long wave infrared LWIR spectral region that result from vibrational and rotational transitions. They are fabricated from high optical quality Fused Quartz, Flint Glass, and Tellurium Dioxide, or other acousto-optic materials with Brewster cut optical faces or durable hard oxide AR coatings for high optical power applications.
Most importantly, it comes with an economic price tag. It is a solid state device with no mechanical moving parts and is immune to vibration. It functions as a tunable transmissive filter. Other materials and models are available. The combination of atomic emission signatures derived from conventional UVN LIBS and fingerprints of intact molecular entities determined from LWIR LIBS acquired in one single measurement surmise bromrose be a very powerful spectral technique for rapid and in-situ chemical, biological, and explosives analysis in security applications.
The utilization of the AOTF into the imaging system offers unmatched spectral flexibility in terms of scanning speed over the full range or random hopping on wavelengths of interest. The Brimrose free space Q-switches are designed for the highest conversion efficiency of RF energy into acoustic energy by attaching the transducer to the crystal with an advanced vacuum metallized process.

Brimrose AOTF HSI is a cost effective, rugged, brimrlse compact design that offers superior speed, image performance, high signal to noise ratio, wide field of view and is suitable for various food, biomedical, pharmaceutical and military applications. LIBS is a laser-ablation based spectroscopic technique.
aon The target interacts with the laser-induced micro-plasma at surface. The AOD changes the diffraction angle of an input laser beam and its angular position is linearly proportional to the RF frequency, so that the higher the frequency, the larger the diffracted angle. H — High Resolution. If the incident acoustic wave is introduced in the direction of the incident optical wave, the laser frequency shifts towards the higher side.

A cavity dumper offers high peak power and higher repetition frequencies. First, lasers are used to corral the atoms and slow them down, stealing their energy and reducing the temperature to approximately microKelvin.
It is necessary to adjust the resonant laser cavity mode spacing frequency to be equal to twice the original acoustic wave frequency to achieve mode locking. The unit is USB-capable, has removable memory and includes a touchscreen display.

During am plasma evolution, ionic and atomic breakdown products, vapor, liquid, and solid phases of target materials all present at the target sample surface. Due to a Doppler shift, the frequency of the diffracted first order optical beam in the AO modulator or AO frequency shifter is shifted in frequency wavelength by brirmose acoustic carrier frequency wavelength.
UH — Ultra high Resolution. Receive press releases from Brimrose Corporation: Email this page to a friend.
EH — Extra high Resolution. Brimrose Acousto-Optic Deflectors AODs combined with RF drivers are specially designed for high-speed scanning applications such as laser recording, optical scanning, signal processing, etc.
It is a fiber-coupled, solid-state device that can tune laser light to very specific frequencies while switching on and off in less than nanoseconds. It will provide scientists with an improved set of tools for probing the realm of quantum mechanics, which is the study of nature at the very smallest scale.

TE cooled enclosures are available upon request. The RF Drivers are provided with either analog amplitude modulation, TTL, or a combination of both, depending upon application requirements. The modulators are used to control laser beam intensity, frequency modulation, frequency shifting, to control pulses and more.
Q-switches are special modulators designed for use inside laser cavities. In one year, the CAL instrument is expected to be fitted by astronauts with a new atom trapping cell that is currently being designed to deliver the AOM light pulses to the atoms.
These are chilled to a fraction of a degree above absolute zero, or even colder than the average temperature of deep space. As a result, nearly all the laser energy nrimrose dumped out of the resonant cavity in the form of a single optical pulse. The AOMs are offered with conduction and water cooled enclosures.
