Attempts at solar-pumped lasers have been reported since 1963. This is unsurprising, as it mirrors the timeline for when the modern environmental movement was gaining traction worldwide, but especially in ...

Nanotechnology continues to fascinate us with smaller and smaller devices. Engineers all around the world are constantly pushing and perfecting our manufacturing capabilities to fit more devices within a ...

Nanowires are truly one-dimensional structures that are long in one direction and short on the lateral dimension. This dimensional reduction gives rise to interesting new phenomena such as quantized ...

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, ...

High power lasers are used in the industry routinely for cutting, drilling, welding and micromachining materials. They have also found applications in medicine where tissue needs to be cut or heated. The ...

Edge emitting and surface emitting lasers present two configurations for laser emission using semiconductors. Edge emitting lasers came first but were quickly replaced by surface emitting lasers for ...

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 ...

Optogenetics is the emerging field of using light to control and study neuronal activity. In 2005, a Stanford University team was able to use a light-sensitive microbial protein to control the timing of ...

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 ...

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 ...
