Introduction to Optical Parametric Oscillators In 1961, Peter Franken and his group at the University of Michigan were the first to use  nonlinear materials to produce optical harmonics. This method ...

Forensic science has come a long way since the 700s, when the Chinese first established the concept of utilizing fingerprints as means of identification. Since then, technology in photonics and optics ...

Introduction A single human hair is approximately 80,000-100,000 nanometers wide. Now, imagine a distance that measures several hundred times smaller than a human hair. Such small distances are often ...

Introduction to Raman Microscopy Raman microscopy is a laser-based spectroscopic technique used to observe molecular vibrations. It is frequently utilized in chemistry to provide a “fingerprint” ...

Introduction to Electro-Optic Modulators (EOM) As discussed in last week’s article, optics research requires precisely controlling the responsive and unwieldy entity of light. Advancements in electro-optic ...

Adaptive Optics Introduction The field of optics studies the behavior of light – a form of substance with a characteristic wavelengths ranging from about 400 to 700 nanometers for visible light to as ...

Ever since x-ray was first discovered by Sir Wilhelm Röntgen, scientists have started the enthusiastic exploration of its potential for imaging applications. Among all the sub-fields, x-ray microscopy has ...

General Information Mica is a naturally occurring birefringent biaxial crystal. It is cleaved into wafers of precisely controlled thickness to produce optical retarders at user-specified wavelengths. Due ...
