Abstract

The history of fluoride laser ceramics begins in 1964 [1], but it was the preparation of fluoride laser ceramics via the hot forming technique that provided a tremendous boost in this area of research and manufacturing.  This method is based on the plastic deformation of the single crystals at high temperatures [2-4].  Application of this technique allowed to obtain lasing in fluoride ceramics of CaF2, SrF2, (Ca,Sr)F2, (Sr,Ba)F2 doped with a number of RE3+ ions such as Yb3+, Nd3+, Pr3+, Tm3+, and Er3+ [2-9] (example of CaF2:Yb ceramics is shown in Fig.1).  The investigated ceramic samples have demonstrated spectral and laser properties similar to that of single crystals.  At the same time, the use of an alternative classic technique of powder precursors hot pressing resulted in significant improvement of the mechanical properties of prepared laser ceramics, while maintaining nearly the same optical and lasing properties [8], as well as thermal conductivity, thermal expansion, heat capacity, microstructure, etc. [4,9-11] as hot formed laser ceramics.
