Mode-Locked Lasers Improved With Graphene Technology
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. ...
Photobleaching Using Lasers for Teeth Whitening in Dentistry
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 ...
Dental Caries Diagnosis Using Fluorescence Imaging Techniques
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 ...
Photocoagulation Using Lasers for Treating Diabetic Retinopathy
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 ...
Holmium Lasers: The Solid State Laser for Lithotripsy
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 ...
Transmyocardial Surgery: Using Lasers to Increase Vascular Flow
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 ...
Nonlinear Imaging to Characterize the Microenvironment of Tumors
Developing a clear characterization of a tumor’s microenvironment is imperative in understanding its progress. A new approach to determining cancer’s development involves a thorough study of ...
Biophysical Cancer Analysis via Raman Spectrometry
A research team from the University of Texas at Austin has published their findings on using Raman spectrometry for biophysical cancer analysis to analyze skin cancer. Their findings were applied to assist ...
Medical Lasers: A Guide to Various Effects and Choices
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 ...
Laser Cooling: A Future for Cryogenics Without Liquid Coolants
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 ...
