Ceramic Laser Materials and Components

Monolithic composite laser materials with undoped caps can be produced directly from ceramics [67-74]. An alternative way is the use of undoped material to clad the laser-active materials with any shape, in which the undoped material can serve to enhance dissipation of heat and even guide the laser radiation. In this case, there is diffusion of doping ions into the undoped part, which has been studied by various methods [75-79]. It is found that in case of Nd YAG, a diffusion layer with the thickness of up to tens of micrometers can be formed, depending on the fabrication process. 

Very complex laser materials for multiple total-reflection active mirrors (TRAM) have also been produced by using ceramic techniques [80-82]. Composite multifunctional monolithic components consisting of the active material and a proper
