An Er:YAG laser (erbium-doped yttrium aluminium garnet laser, erbium YAG laser) is a solid-state laser whose active laser medium is erbium-doped yttrium aluminium garnet (Er:Y 3 Al 5 O 12). Er:YAG lasers typically emit light with a wavelength of 2940 nm , which is infrared light .
Nd:YAG (neodymium-doped yttrium aluminum garnet; Nd:Y 3 Al 5 O 12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant , neodymium in the +3 oxidation state, Nd(III), typically replaces a small fraction (1%) of the yttrium ions in the host crystal structure of the yttrium aluminum garnet (YAG), since the two ions are ...
Laser rods (from left to right): Ruby, Alexandrite, Er:YAG, Nd:YAG The active laser medium (also called a gain medium or lasing medium ) is the source of optical gain within a laser . The gain results from the stimulated emission of photons through electronic or molecular transitions to a lower energy state from a higher energy state previously ...

In 2016, MDCalc launched an iOS app, [7] followed by an Android app in 2017. [8] A 2017 survey estimated 65% of U.S. attending physicians and 79% of U.S. resident physicians use MDCalc regularly. [ 1 ]
Use of the dental laser remains limited, with cost and effectiveness being the primary barriers. The cost of a dental laser ranges from $4,000 to $130,000, where a pneumatic dental drill costs between $200 and $500. Hard tissue lasers are incapable of performing some routine operations in the treatment of cavities. [17]
Since 2019, wedding costs have grown nearly 20% in the U.K. and 8% in France, but just 2.7% in the U.S. Some have cut their budgets—in Spain, costs are down 1.7%, and in Canada, they're down ...
Neodymium-doped yttrium orthovanadate (Nd:YVO 4) is a crystalline material formed by adding neodymium ions to yttrium orthovanadate.It is commonly used as an active laser medium for diode-pumped solid-state lasers.
