crystals, is the most appropriate for a wide range of medical applications due to its physical properties, such as the lasing wavelength and tunability. Indeed, alexandrite is the first of a class of tunable solid-state laser materials. It features a broad tuning wavelength range, 710 \u2013 800 nm, with capability to store and efficiently extract multi-J energy pulses.<br \/>It is one of the most robust solid-state laser materials available with a\u00a0<em>thermal shock resistance<\/em>\u00a0five-times that of Nd:YAG.<\/p><p>It offers applications in dermatology, lithotripsy, dental, spectrosocopy, atmospheric LIDAR, testing of fiber optics and photodetectors, materials processing, pumping of dye lasers, non-linear optics studies and annealing of semiconductors.<\/p><p>Alexandrite lasers emit at a wavelength of 755 nm, that is well within the absorption spectrum of melanin in the skin, resulting in hypopigmentation, and enabling the use of these lasers for treatment of pigmented lesion, such as removal of green\/blue\/black tattoos, brown pigment spots, lentigines and age spots. It\u2019s also used in hair removal and leg vein reduction.<\/p><p>Ultra-pure gas and superior raw material purity, together with a securely controlled proprietary process, allow FILAR OptoMaterials to proudly offer premium grade Alexandrite crystal rods with low losses and higher efficiency.<br \/>Chromium concentration uniformity, along each rod, is achieved by using only a small portion (about 20%) of the melt. A very uniform Chromium profile is certified for each boule, that is also marked for identification.<\/p><p>In-house coating allows a short cycle time after end polishing, assuring high adherence and contamination-free layers.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div
