Yttrium Aluminum Garnet Laser Materials

The Role of Factors Influencing the Optical Properties of Yttrium Aluminum Garnet Ceramic Body

Yttrium Aluminum Garnet (Y3Al5O12) is a transparent ceramic with a wide range of applications such as high mechanical strength windows, high power laser sources and radiation detectors. The most important challenge in making these ceramics is the problem of low light transmittance, especially in the visible area in the range of 400 to 700 nm, which is greatly affected and reduced by various fac...

Yttrium Aluminum Garnet Fibers from Metalloorganic Precursors

Mixtures of yttrium acetate hydrate (Y(O2CCH3)3?4H2O) and aluminum formate hydrate (Al(O2CH)3?3H2O in H2O) or yttrium isobutyrate (Y[O2CCH(CH3)2]3) and aluminum isobutyrate (Al[O2CCH(CH3)2]3) in tetrahydrofuran were used as precursors to process yttrium aluminum garnet (YAG, Al5Y3O12) fibers. The pyrolytic decomposition patterns of Al(O2CH)3?3H2O, Y(O2CCH3)3?4H2O, and a [3Y(O2CCH3)3?4H2O/5Al(O2...

Bulk optical damage thresholds for doped and undoped, crystalline and ceramic yttrium aluminum garnet.

We measured the bulk optical damage thresholds of pure and Nd-doped ceramic yttrium aluminum garnet (YAG), and of pure, Nd-doped, Cr-doped, and Yb-doped crystalline YAG. We used 9.9 ns, 1064 nm, single-longitudinal mode, TEM00 pulses, to determine that the breakdown thresholds are deterministic, with multiple-pulse thresholds ranging from 1.1 to 2.2 kJ/cm2.

Three-photon absorption in Nd-doped yttrium aluminum garnet

This paper presents the results of a study of resonantly enhanced, three-, photon absorption in Nd-doped yttrium aluminum garnet (Y3Alg0~2) or Nd: YAG. The trivalent ions of the rare-earth elements, such as Nd'+, are characterized by energy levels which remain relatively sharp even in a crystalline environment, and thus crystalline solids doped with rare-earth ions present interesting systems i...
