Optical properties and highly efficient laser oscillation of Nd:YAG ceramics

Laser crystals and ceramics: recent advances

“…[280,282,298,299,447]). It is enough to note here the results that were achieved concerning the creation of high-power Nd 3+ :Y 3 Al 5 O 12 ceramic lasers with LD pumping.…”

Phase Separation in Garnet Solid Solutions and its Effect on Optical Properties

“…[ 16,17 ] By contrast, larger rare earths such as Nd 3+ have very limited solubility in YAG [ 18,19 ] and are prone to concentration quenching above ≈ 1 at%. [ 20 ] YAG:Er 3+ has been manufactured in both polycrystalline ceramic and single-crystal forms. The polycrystalline YAG:Er 3+ ceramic is synthesized using a solid-state reaction [ 21 ] while the single-crystal form is produced using conventional melt growth such as micro-pulling or the Czochralski method.…”

“…The polycrystalline YAG:Er 3+ ceramic is synthesized using a solid-state reaction [ 21 ] while the single-crystal form is produced using conventional melt growth such as micro-pulling or the Czochralski method. [22][23][24] Although the spectroscopic properties and laser performance of YAG:R 3+ ceramics (R 3+ = Nd 3+ , Er 3+ , Yb 3+ ) have been shown to be similar to YAG:R 3+ single crystals, [ 14,20,21,25 ] the ceramic form is much easier to fashion into different shapes and is more cost-effective for certain applications such as lasers and phosphors. In the present work, we have shown that formation of a complete solid solution via solid-state synthesis is dependent upon the heat treatment and erbium content.…”

Tailored Ceramics for Laser Applications

“…The solution was aged until the pH stabilized between 7.5 to 11, and then filtered, washed, dried and ball milled for 24 h, before being pressed and sintered as before. Lu et al [100,103] A ten-fold increase in the width of the Nd spectral line allows 10 ps pulses to be produced [106]. Nd:YSAG can be made transparent using the mixed oxide synthesis discussed above for YAG [107].…”
