Abstract

Solar-pumped laser has attracted attention in the area of renewable energy creation. However, since the conversion efficiency from solar energy to laser energy is low, such lasers are not yet in practical use. In this work, we developed Nd³⁺,Cr³⁺ codoped YVO4 and CaYAlO₄ crystals for solar-pumped laser. We succeeded to increase absorption at UV-VIS region with both crystals drastically. The absorption cross section of Nd,Cr:CaYAlO₄around 400 nm was more than 70 times that of Nd,Cr:YAG crystals. The fluorescence at 1 μm was observed by pumping at 400 nm. It indicates that energy transfer from Cr to Nd occurred effectively.
