Abstract

Transparent ceramic laser materials, which were fabricated by a solid-state reaction method, offer numerous advantages over melt growth methods, including faster production times, solid solution allowing the fabrication of multi-phase transition materials, highly homogeneous materials and the ability to engineer profiles and structures before sintering. Much progress has been made in improving the optical quality from ceramics, as well as exploring new materials [1-3]. Successfully developed concentrated Nd:YAG ceramics was opened the way for drastic heat reduction by directly upper laser level pumping [4, 5]. Recently, the advantages of Yb:YAG materials for high-power and highly efficiency lasers are well recognized [6-8]. In this research, we’d like to discuss about high power edge-pumped single crystal Yb:YAG/ceramic YAG composite microchip laser and ultrafast Yb:Y3ScAl4O12 ceramic laser.
