 Hatteras-D femtosecond  transient absorption data acquisition system

Ultrafast spectroscopy provides essential information on the dynamics of physical, chemical and biological molecular events that occur on femtosecond - picosecond - nanosecond time scale. The events are initiated by a femtosecond laser pulse (pump) and the photophysical and photochemical events are probed by another femtosecond laser probe pulse. Del Mar Photonics Hatteras femtosecond  transient absorption spectroscopy system is an ideal tool for ultrafast dynamics research.

Femtosecond Transient Absorption Measurements system Hatteras Femtosecond Transient Absorption Measurements system Hatteras.
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.

In addition to complete Hatteras system we supply custom Data Acquisition Systems for Femtosecond Transient Absorbtion and other ultrafast dynamics techniques. Below is an example of two custom systems.
