Abstract :
Summary form only given. Since powerful, tunable ultraviolet laser sources rely on the frequency-doubling of lasers in the visible range, the search for new nonlinear optical (NLO) materials for ultraviolet and blue-green spectroscopic applications has received increasing attention. In the past few years a new NLO crystal YCa/sub 4/O(BO/sub 3/)/sub 3/ (YCOB) has attracted considerable interest because it exhibits a relatively large second harmonic generation (SHG) effect, and the single crystal is easily grown. Recently a new lanthanum and calcium borate with the composition La/sub 2/CaB/sub 10/O/sub 19/ was identified by our group. This compound possesses the significant feature comparable with that of YCOB. In this paper, we report the linear optical and nonlinear optical properties of La/sub 2/CaB/sub 10/O/sub 19/ crystal (LCB).
