ABSTRACT
Laser ceramics have been well-developed with remarkable advantages allowing for high doping, large-size sample fabrication, homogeneous dopant distribution, optical grade post-processing of low cost, low-threshold broadly tenability, as well as sophisticated but convenient engineering of multilayer structures, which are regarded as promising substitutes for the next generation of laser gain media [1,2]. In particular, effective thermal management of ceramic laser can be achieved by using multilayer ceramics with different doping, which was suitable for the application of a high-power laser [3]. Nowadays, solid-state lasers continue to occupy a prominent place among different kinds of fields. In order to meet the challenging requirements in the areas of laser power, beam quality, efficiency, size and weight, it is essential to optimize the structural designing of laser gain media. Planar waveguide structure (PWs) has peculiarities of low lasing thresholds, high gain, high heat transmission and optical confinement with respect to the traditional uniform bulk laser system, which makes waveguide lasers suitable for high power and compact devices. Taking the advantages of both the RE:YAG ceramics and the planar waveguide structure, it is very promising to construct a compact, efficient and high power solid-state laser. In this work, composite YAG/RE:YAG/YAG (RE =Nd, Yb, Tm, Ho) transparent ceramics for planar waveguide lasers were fabricated by tape casting and vacuum sintering [4]. The fabrication and characterizations of planar waveguide laser ceramics were mainly discussed in this paper [5,6].
