As early as the end of the 1960s, people already put forward an idea of LSFD crystal.In 1979 V. G. Dmitriev et al. first produced LSFD Nd:LN crystal and observed thephenomenon of LSFD in their laboratory. In 1981 L. M. Dorozhkin et al. reportedthe LSFD effect of NYAB crystal from 1.32μm to 0.66μm. In 1990 N. Y. Chou etal. first briefly reported the investigation on the third LSFD Cr:KTP crystal. Be-fore 1990 we had begun to study the Cr:KTP crystal in our laboratory.
