Raman scattering phenomenon can be used to engineer broadband tunable lasers and to generate a broad band of frequencies in the IR spectrum. These light sources are instrumental for probing and detecting ...

For any high-sensitivity laser application, it is essential that all necessary characteristics of the laser beam in use can be quantified and characterized beforehand. To this end, we have written ...

  An Introduction to Nanophotonics: Something Big from Something Small In recent years there has been a lot of work with nanophotonics in optical physics and engineering. This is a part of the rising ...

As we have noted several times previously on our blog, Moore’s law, the phenomenon of exponential growth of computing power due to ever more compact transistor technology, can only continue so far ...

Introduction to Elastography Elastography is a type of imaging modality that provides information on the elastic properties and stiffness of the tissue being reviewed based on spatial distribution. It is ...

Comparison Between Laser Diode-Pumped Light Sources, LEDs, and HIDs There is a great push in society today to offer light sources that are brighter, clearer, and more energy efficient. For many years now, ...

Nitrogen vacancy centers in diamond are an exciting platform to build very accurate sensors. These vacancy centers provide very precise energy levels that can be influenced and controlled by various ...

Introduction to Presbyopia As we grow older the lens of the eye becomes much more rigid, hindering the ability to properly focus light onto the retina. This condition, presbyopia, affects approximately two ...

Scientists have spent many years looking at different ways of treating various types of medical conditions. This includes mental/psychological conditions such as depression, and physical ailments like ...

Quantum dots, sometimes referred to as semiconductor nanocrystals, are an exciting emerging technology that we have covered previously on our blog. Quantum dots are artificial nanoparticles (on the order ...
