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 ...

Laser marking of metals is becoming an increasingly important process in product identification and branding. On our blog, we have previously written about the basic principles of laser marking, the proper ...

In 1963, Leon Goldman became the first person to report using lasers in dermatology. Goldman reported the effects of Ruby laser in the selective destruction of cutaneous pigmented structures, like black ...

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 ...

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 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 ...
