Abstract

The invention discloses a Nd<3+> doped (Y1-xScx)2O3 laser transparent ceramic and a preparation method thereof, and belongs to the technical field of special ceramic material manufacturing processes. The Nd<3+> doped (Y1-xScx)2O3 laser transparent ceramic is prepared from such raw materials as high-purity Nd2O3, Y2O3 and Sc2O3 nano-powders by use of a solid-phase sintering method under the condition of a relatively low temperature. Proven by checking experiments, the Nd<3+> doped (Y1-xScx)2O3 laser transparent ceramic prepared by use of the method has a relatively wide emission bandwidth, and can be applied to realize ultra-short mode-locked pulse laser output. Compared with the existing Y2O3-Sc2O2 system single crystal, the Nd<3+> doped (Y1-xScx)2O3 laser transparent ceramic is simple in preparation process, low in manufacturing cost, and advantageous for industrial large-scale production; the types of the solid laser materials in the field are increased.

Description

technical field [0001] The invention relates to a ceramic material and a preparation process thereof, in particular to a solid laser ceramic material and a preparation process thereof, which are applied in the technical field of laser gain medium and special ceramic manufacturing process. Background technique [0002] Since the advent of pulsed lasers, ultrashort pulsed lasers have played an increasingly important role in the fields of ultrafast physics, biology, and chemistry. Titanium sapphire (Ti:Al 2 o 3 ) laser is currently the ultrafast laser device that can obtain the shortest pulse and is most used. However, the pump source used in it has the disadvantages of large volume, low electrical efficiency, and high price, which limits its development as a commercial femtosecond laser to a portable and low-cost direction. The rapid development of high-power diode semiconductor lasers (LD) has given Yb-doped 3+ The application of laser materials in the femtosecond laser f...
