Goldman is considered a leading medical authority around the world and has authored 14 medical textbooks, some in 2nd, 3rd, 4th, 5th, and 6th editions, on cosmetic and laser surgery, dermatology, sclerotherapy, ambulatory phlebectomy, and cellulite, several of which are considered definitive medical texts in their respective fields—as well as ...
Weiss is the director and co-founder of Maryland Laser Skin and Vein in Baltimore, MD. He is a former associate professor of dermatology at Johns Hopkins University, and is currently a clinical associate professor of dermatology at University of Maryland School of Medicine. [3]
Peyman was born in Shiraz, Iran.At the age of 19, he moved to Germany to begin his medical studies. He received his MD at the University of Freiburg in 1962. [citation needed] He completed his internship at St. Johannes Hospital in Duisburg, Germany in 1964 and at Passaic General Hospital in Passaic, New Jersey in 1965.
A coherent perfect absorber (CPA), or anti-laser, is a device which absorbs coherent waves, such as coherent light waves, and converts them into some form of internal energy, e.g. heat or electrical energy. [1] [2] It is the time-reversed counterpart of a laser. [3]
Leon Goldman (1906 – December 2, 1997) was an American dermatologist and a pioneer in laser medicine. [1] [2] [3] His research areas included the application of lasers in dermatology, [2] [3] cancer photodynamic therapy (PDT) [4] and the use of organic dyes in PDT.
M 2 is useful because it reflects how well a collimated laser beam can be focused to a small spot, or how well a divergent laser source can be collimated. It is a better guide to beam quality than Gaussian appearance because there are many cases in which a beam can look Gaussian, yet have an M 2 value far from unity. [1]
The pump laser can be seen entering the dye jet, beneath the yellow window. A dye laser is a laser that uses an organic dye as the lasing medium, usually as a liquid solution. Compared to gases and most solid state lasing media, a dye can usually be used for a much wider range of wavelengths, often spanning 50 to 100 nanometers or more.
The Lockheed Martin AN/AAS-35(V) Pave Penny is a laser spot tracker carried by US Air Force attack aircraft and fighter-bombers to enable them to track a laser spot on the ground. It is a receiver only, allowing the pilot to see which targets marked by a laser designator. Pave Penny does not produce a laser beam and cannot be used to designate ...
