Abstract
Infrared lasers at 1 μm are widely used in numerous industrial or medical applications, optical communication and spectroscopy. The lasers available nowadays are based on different laser active media, among which most common used are Nd:YAG, Yb:YAG, Nd:YVO4, or Nd:GdVO4, to mention few of them [1]. In addition, visible laser sources are obtained by using the infrared laser emission in conjunction with highly efficient nonlinear crystals. Furthermore, if the nonlinear crystal is doped with Nd3+ ions, then a compact, more efficient and lowercost self-frequency conversion laser system could be realized. Thus, the research for finding new laser crystals or nonlinear crystals with prominent self-frequency doubling properties is of great interest in present, owing mostly to the need for up-scaling the existing laser systems.
