Ruby laser weaknesses in the lining. Ruby lasers were used extensively in tattoo and hair removal, but are being replaced by alexandrite and s in this application. The ruby laser was the first laser to be made functional. Built by Theodore Maiman in 1960, the device was created out of the concept of an "optical maser," a maser that could operate in the visual or infrared regions of the spectrum. In 1958, after the inventor of the maser, Charles Townes, and his colleague, Arthur Schawlow, published an article in the "Physical Review" regarding the idea of optical masers, the race to build
Trident laser Back-scatter (FABS) diagnostic at the National Ignition Facility. A new front-end for the laser employs a 2nd order cleaning technique, dubbed SPOPA (for Short-Pulse Optical Parametric Amplification) cleaning, which reduces the contrast to better than 10 ASE intensity ratio, making it one of the cleanest ultra high-intensity high-power laser in the world. The laser is currently being used for Fast Ignition ICF research, warm dense matter experiments, materials dynamics studies, and laser-matter interaction research, including particle acceleration, x-ray backlighting and laser-plasma instabilities (LPI).
