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 ...
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 ...
Diode Lasers for Cytometry: Cell Counting and Sorting
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 ...
Airborne LiDAR and Bathymetry
It is a widely touted fact that humans have yet to explore 95% of the Earth’s oceans. This is because water pressure makes deeper parts of the ocean implausible to reach. Explorers also risk loss of life ...
Lasers in Ophthalmology: The Future is Clear
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 ...
Diode Laser: The Most Versatile and Convenient Coherent Light Source
Introduction to the Diode Laser Researchers have been developing different types of coherent light sources to fit a larger span of applications since 1960. Present-day lasers vary in size, power-range, and ...
