Basics of Lamp-Pumped Solid State (LPSS) Lasers As the trailblazer for many modern day laser designs, LPSS lasers are a mature technology that have been around since the invention of the first laser. The ...

Introduction to Diffraction Gratings Diffraction gratings are optical components that diffract and separate light into several beams at different angles by wavelength. Their working principle is hinged ...

Introduction to Ultrafast Lasers The ultrafast laser is a category of laser that emits ultrashort light pulses with time spans of femtoseconds or picoseconds. To put this in perspective, ultrafast lasers ...

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 ...

Basics of Operation There are many different types of lasers available in todays photonics market, however, Diode Pumped Solid State (DPSS) laser systems are a reliable and widely-used technology. Simply ...

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 ...

How do lasers work? This blog spends much time discussing the use and the applications of lasers, but how do they work? Lasers emit a coherent light beam from a cavity. The term “laser” is actually an ...

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 Elemental Analysis All matter on Earth is composed of an assortment of 118 elements. The possible combinations are endless, with varying quantities of molecules and components in a ...

Introduction: Acousto-Optic Modulator Optical setups require extreme precision, and researchers must often implement modulators to adjust the frequency, amplitude, wavelength, and direction of their laser ...
