What is Yb:YAG crystal
Ytterbium-doped YAG (Yb: YAG) is a kind of active laser crystal with laser wavelength of 1030 nm, which is among the most appealing laser active materials. Ytterbium-doped yttrium aluminum garnet laser crystal has a broad absorption band of 18 nm at 940 nm. It is among one of the most helpful crystals for high power diode-pumped solid-state lasers as well as is preferable for diode-pumped than traditional neodymium-doped crystals. It can pump 0.94 µm and also produce 1.03 µm laser result.
What are the advantages of Yb:YAG compared with Nd:YAG
Contrasted to typically made use of Nd: YAG crystals, Yb:YAG crystals have a bigger absorption bandwidth to reduce thermal administration needs on diode lasers, a longer upstate life time, and also a 3 to 4 times lower thermal load each pump power. The focus of the dopant ranges from 0 to 30% of the replaced yttrium atom. The Yb: YAG fractional heating is really reduced, slope efficiency is really high, no ecstatic state absorption and upconversion, high mechanical toughness, high thermal conductivity. Ytterbium-doped YAG can be pumped by trusted InGaAs laser diodes at 940 or 970 nm.
Ytterbium-doped yttrium aluminum garnet crystals are anticipated to replace Nd: YAG crystals for high-power diode-pumped lasers and various other prospective applications, such as their doubling wavelength of 515 nm, which is really near to the increasing wavelength of Ar ion lasers (514 nm), making it a sensible option to big quantity argon ion lasers.
Yb: YAG shows terrific potential as a high power laser product. Industrial lasers are being developed for a selection of applications, such as steel cutting and also welding. With top quality Yb: YAG now available, much more areas as well as applications are being checked out.
The advantages of Ytterbium-doped YAG laser crystal
The benefits of Ytterbium-doped YAG are excellent pump transmission capacity and also transfer random sample. It is perfect for diode pumping. The wide absorption band allows Yb: YAG to preserve nonstop pumping performance throughout normal thermal shifts in the diode result. High efficiency suggests that Ytterbium-doped YAG laser crystals of reasonably small size will certainly produce high power result. Based on the YAG master crystal, Ytterbium-doped yttrium aluminum garnet can be swiftly integrated right into the laser design procedure. This combination of functions enables straightforward as well as elegant laser styles as well as makes it simpler to produce high-power lasers.
