Abstract

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

Comparative study of Ho:Y2O3 and Ho:Y3Al5O12 transparent ceramics produced from laser-ablated nanoparticles

“…As for laser ceramics with a garnet structure, a soft mixing procedure can be used instead of the planetary ball milling as nanoparticles are weakly agglomerated. This approach allowed to precisely control the stoichiometry leading to good optical quality [27,28].…”

Specifics of Spectroscopic Features of Yb3+‐Doped Lu2O3 Laser Transparent Ceramics

“…It means 77% of transmission for thickness of 1 mm. To compare, for the Yb 3þ -doped Lu 2 O 3 ceramics disk reported earlier, [40] the transmission for 1 mm thickness is 81.3% at 1100 nm, with the same Fresnel transmission of 81.5% corresponding to a refractive index n ¼ 1.909.…”

“…At the same time, Jing et al measured the corresponding set of 2 F 5/2 energy levels for Yb 3þ -doped Lu 2 O 3 at 10 250 cm À1 , 10 703 cm À1 , and 11 067 cm À1 , [40,41] revealing a rather large discrepancy of the position of the level (6) at 10 703 cm À1 with respect to this measurement (10 537 cm À1 ) from absorption spectrum at 4.2 K and also with Ikesue's measurement (10 530 cm À1 ) in the study by Ikesue et al [9] 5.4. Attempt to Assign the 2 F 7/2 Stark Levels…”

Growth, Structure, Spectroscopy, and Laser Operation of a “Mixed” Yb:(Y,Lu)3Al5O12 Garnet Crystal

“…The growth process, thermal properties, spectroscopic characteristics, and laser performance of Yb:LuAG crystals have already been detailed in previous literature [7]. It's worth noting that Yb 3+ -doped LuAG can also be produced using transparent ceramic technology [10,17], enabling efficient laser operation with ceramics [11,18].…”
