Promising ceramic laser material: Highly transparent Nd3+:Lu2O3 ceramic

Abstract

A solid-state laser material based on highly transparent cubic Nd3+:Lu2O3 ceramic was developed using nanocrystalline technology and a nonpress vacuum sintering method. Spectroscopic properties of this ceramic laser material were investigated. At room temperature under single-laser diode pumping, efficient continuous wave laser oscillation was demonstrated at two wavelengths of the 4F3/2→4I11/2 channel. The potential application of such a laser material was also discussed.

Laser oscillation and luminescence of Nd³⁺- and Eu³⁺-doped Lu₂O₃ transparent ceramics fabricated by spark plasma sintering

“…By using the straight cavity configuration, the maximum output power was 0.2 W and the slope efficiency was 14% (filled circles in Fig. 14), 25) which is comparable to that of the Nd 10) and single crystal (17% for 1 at.% Nd 3+ ). 4) By using the V-type cavity configuration, the maximum output power of 0.6 W and the slope efficiency was 7% (open circles in Fig.…”

Tailored Ceramics for Laser Applications

“…Lu et al [119] ples presumably obtained using the same urea process. They also analyzed phonon transmission and scattering at grain boundaries using the heat-pulse technique at liquid helium temperatures.…”

Preparation and characterization of transparent Nd:YAG ceramics

“…Two types of ceramics processing were successfully demonstrated: l "wet" method developed by Yanagitani and Ueda group [4][5][6][7][8], l "dry" method developed by group of Ikesue and Taira [1][2][3]9]. The ceramics made of polycrystalline Y 3 Al 4 O 12 [1][2][3][4][5]14,15,32,33], Lu 3 Al 4 O 12 [13], Y 2 O 3 [6,8,16,18,19,21,22], and Y 3 ScAl 4 O 12 [9] doped with neodymium, ytterbium, chro− mium, and erbium were prepared and showed excellent per− formance in experiments.…”
