Laser pumping. Nd:YAG lasers, mainly via their second and third harmonics, are widely used to excite dye lasers either in the liquid or solid state. They are also used as pump sources for vibronically broadened solid-state lasers such as Cr 4+:YAG or via the second harmonic for pumping Ti:sapphire lasers. … See more Nd:YAG (neodymium-doped yttrium aluminum garnet; Nd:Y3Al5O12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant, triply ionized neodymium, Nd(III), typically replaces a small … See more For many applications, the infrared light is frequency-doubled or -tripled using nonlinear optical materials such as lithium triborate to obtain visible (532 nm, green) or See more 1. ^ Koechner §2.3, pp. 48–53. 2. ^ Geusic, J.

WebDye lasers are the original tunable laser sources. Usually pumped with the second or third harmonic (532nm or 355nm) of an Nd:YAG laser, they have broadly tunable, narrow linewidth outputs from the near UV to the near IR. Typical Nd:YAG lasers have pulse durations in the … WebJul 1, 1995 · Optical pumping is usually accomplished with krypton arc lamps because the near-IR emission lines of krypton gas are a good match for the strong absorption lines of Nd:YAG. However, the advent of diode-laser arrays such as gallium aluminum arsenide … bearing buddy bra 1980
