    femtosecond  transient absorption data acquisition system Future nanostructures and biological nanosystems will take advantage not only of the small dimensions of the objects but of the specific way of interaction between nano-objects. The interactions of building blocks within these nanosystems will be studied and optimized on the femtosecond time scale - says Sergey Egorov, President and CEO of Del Mar Photonics, Inc. Thus we put a lot of our efforts and resources into the development of new Ultrafast Dynamics Tools such as our Femtosecond Transient Absorption Measurements system Hatteras. Whether you want to create a new photovoltaic system that will efficiently convert photon energy in charge separation, or build a molecular complex that will dump photon energy into local heat to kill cancer cells, or create a new fluorescent probe for FRET microscopy, understanding of internal dynamics on femtosecond time scale is utterly important and requires advanced measurement techniques.

 Frequency-stabilized CW single-frequency ring Dye laser DYE-SF-007 pumped by DPSS DMPLH laser installed in the brand new group of Dr. Dajun Wang at the The Chinese University of Hong Kong. DYE-SF-077 features exceptionally narrow generation line width, which amounts to less than 100 kHz. DYE-SF-077 sets new standard for generation line width of commercial lasers. Prior to this model, the narrowest line-width of commercial dye lasers was as broad as 500 kHz - 1 MHz. It is necessary to note that the 100-kHz line-width is achieved in DYE-SF-077 without the use of an acousto-optical modulator, which, as a rule, complicates the design and introduces additional losses. A specially designed ultra-fast PZT is used for efficient suppression of radiation frequency fluctuations in a broad frequency range. DYE-SF-077 will be used in resaerch of Ultracold polar molecules, Bose-Einstein condensate and quantum degenerate Fermi gas and High resolution spectroscopy  |

CIE division scheme
The International Commission on Illumination (CIE) recommended the 
division of infrared radiation into the following three bands:[5]
IR-A: 700 nm–1400 nm (0.7 µm – 1.4 µm)
IR-B: 1400 nm–3000 nm (1.4 µm – 3 µm)
IR-C: 3000 nm–1 mm (3 µm – 1000 µm)
A commonly used sub-division scheme is:[6]
Near-infrared (NIR, IR-A DIN): 0.75-1.4 µm in wavelength, defined by the water 
absorption, and commonly used in fiber optic telecommunication because of low 
attenuation losses in the SiO2 glass (silica) medium. Image intensifiers are 
sensitive to this area of the spectrum. Examples include night vision devices 
such as night vision goggles.
Short-wavelength infrared (SWIR, IR-B DIN): 1.4-3 µm, water absorption increases 
significantly at 1,450 nm. The 1,530 to 1,560 nm range is the dominant spectral 
region for long-distance telecommunications.
Mid-wavelength infrared (MWIR, IR-C DIN) also called intermediate infrared 
(IIR): 3-8 µm. In guided missile technology the 3-5 µm portion of this band is 
the atmospheric window in which the homing heads of passive IR 'heat seeking' 
missiles are designed to work, homing on to the IR signature of the target 
aircraft, typically the jet engine exhaust plume.
Long-wavelength infrared (LWIR, IR-C DIN): 8–15 µm. This is the "thermal 
imaging" region, in which sensors can obtain a completely passive picture of the 
outside world based on thermal emissions only and requiring no external light or 
thermal source such as the sun, moon or infrared illuminator. Forward-looking 
infrared (FLIR) systems use this area of the spectrum. Sometimes also called the 
"far infrared."
Far infrared (FIR): 15 - 1,000 µm (see also far infrared laser).
NIR and SWIR is sometimes called "reflected infrared" while MWIR and LWIR is 
sometimes referred to as "thermal infrared." Due to the nature of the blackbody 
radiation curves, typical 'hot' objects, such as exhaust pipes, often appear 
brighter in the MW compared to the same object viewed in the LW.

Infrared Detectors and Systems (Wiley Series in Pure and 
Applied Optics)
E. L. Dereniak (Author), G. D. Boreman (Author) 
Product Description
This text covers the range of subjects necessary for the understanding of modern 
infrared-imaging systems at a level appropriate for seniors or first-year 
graduate students in physics or electrical engineering. The first six chapters 
focus on fundamental background issues of radiation detection, beginning with 
the basics of geometrical optics and finishing with a discussion of the figures 
of merit used for describing the signal-to-noise performance of a detector 
system. Other topics include radiometry and flux-transfer issues, basic 
radiation-detector mechanisms, and random-process mathematics.
The presentation then moves on to specific detector technologies and the 
fundamental mechanisms of detection, paying special attention to responsivity 
and noise performance. Devices discussed include photovoltaic detectors, 
photoconductive detectors, thermal detectors, Schottky-barrier diodes, and 
bandgap-engineered photodetectors via multiple quantum wells and superlattices.
The book concludes with a close look at infrared detection systems and related 
issues. In the discussion of infrared search systems, the range equation is 
developed in terms of the optical and detector parameters of the system. A 
separate chapter is devoted to modulation transfer function, a 
spatial-frequency-domain description of image quality. The final chapter 
describes the design equations for thermal-imager systems in terms of 
noise-equivalent temperature difference and minimum resolvable temperature.
Supported and clarified by 470 illustrations and accompanied by an extensive 
glossary of the nomenclature, this is an excellent text for graduate and senior 
level courses in radiometry and infrared detectors. It is also a valuable 
reference for practicing engineers involved in the use, design, analysis, and 
testing of infrared detector-based systems.
Infrared Detectors and Systems is a complete, accessible, and timely exposition 
of a technology whose applications are increasingly important and widespread. 
Based on courses presented by two of the field's leading figures, this book 
provides extensive coverage of the background and fundamentals of radiation 
detection and goes on to examine specific technologies and systems in depth and, 
in some cases, for the first time in print.
Technologies discussed include
* Photovoltaic detectors
* Photoconductive detectors
* Thermal detectors
* Schottky-barrier diodes
* Bandgap-engineered photodetectors via multiple quantum wells and superlattices
Supplemented with 470 illustrations and a complete glossary of the nomenclature, 
this is the ideal text for senior- and graduate-level courses in radiometry and 
optical detection.
