A research team from the Military Technical College and from Cairo University in Cairo, Egypt have developed a fluorescence hyper-spectral imaging system which can be employed for diagnosis and detection ...

Lasers came into the field of ophthalmology in 1961, when Ruby laser was used to create ocular lesions in rabbits. Unfortunately, creating vascular lesions in the human retina was not effective at that ...

Cardiovascular diseases are among the top causes of death and morbidity in developed nations. In particular, diseases of the coronary arteries are most prevalent. Lasers are well suited to diagnose and ...

The first medical application of lasers was reported by Goldman in 1962. In cardiovascular surgery, McGuff first used a Ruby laser in 1963 for the experimental ablation of atherosclerotic plaques. After a ...

Low temperature physics has helped us produce exotic quantum materials such as superconductors. This usually requires cryogenic fluids such as liquid nitrogen and helium for operation. Recently cooling ...

Since the first demonstration of the laser in 1960, people have endeavored to make lasers more compact. Semiconductor lasers achieved this desired compactness employing so called heterostructures. This ...

Since the invention of the first operating laser in 1960, lasers have been designed in various regions of the electromagnetic spectrum and output powers. Soon after the advent of semiconductor fabrication ...

A team of researchers from Keio University in Japan has published their results on utilizing laser processing to produce biodegradable polymers for use in tissue engineering. Biocompatible polymers are ...

The Very Large Telescope – located in northern Chile- is one of the world’s most advanced optical instruments.  The VLT consists of four unit telescopes capable of high-resolution spectroscopy and ...

Microfluidics is the field of science and engineering that involves itself with fluids at a sub-millimeter scale. Many biological, chemical, and physical processes either occur or can be simulated at such ...
