Optical fibers are a convenient instrument for robust light transfer. Their low losses have enabled their wide use in long distance telecommunication systems while service providers like AT&T, Verizon ...

Non-linear techniques in photonics have opened up new avenues for sensing and manipulating materials. In the 1960s, non-linear techniques were used to discover multiphoton absorption processes in ...

Tissue welding is a relatively new procedure that aims to seal wounds and openings in a surgery using laser. The first tissue welding application using lasers was done in 1964 to join small blood vessels ...

A research team at Keio University in Japan devised a novel handheld viscosity sensor capable of quick, non-contact in situ measurements. Viscosity is a fundamental property for liquid analysis in a wide ...

Ever since graphene sheets were isolated from bulk graphite in 2004, two-dimensional materials have received an immense amount of interest for their unexpected and novel electronic and optical properties. ...

Lasers in dentistry have been explored since the early 1960s. At its infancy, the practitioners of the field used Ruby lasers. They used the pulses emitted from such lasers to ablate the tooth enamel to ...

Human beings have suffered from kidney stone problems since 7000 BC. Despite advances in treatment, incidence of renal stone disorder has increased over the past few decades. Lasers have been used to ...

LASERs (or Light Amplified by Stimulated Emission of Radiation) are among the most widely available and versatile optical tools today.  A variety of lasers are commonly used in household devices, such as ...

A group of South Korean researchers recently published research revealing a new and innovative way to treat colorectal cancer and precancerous tissues using non-ablative fractional lasers (NAFLs). This new ...

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 ...
