M. Iwai et al., CRYSTAL-GROWTH AND OPTICAL CHARACTERIZATION OF RARE-EARTH (RE) CALCIUM OXYBORATE RECA1O(BO3)(3) (RE=Y OR GD) AS NEW NONLINEAR-OPTICAL MATERIAL, JPN J A P 2, 36(3A), 1997, pp. 276-279
We report on the growth of GdCa4O(BO3)(3)(GdCOB) and YCa4O(BO3)(3)(YCO
B) crystals and their characterization as new nonlinear optical materi
als. The crystals with good optical quality were grown by the Czochral
ski method. YCOB, the characteristics of which has not previously been
reported to our knowledge, has a larger temperature acceptance bandwi
dth than that of GdCOB, and third harmonic generation of a Nd:YAG lase
r in this crystal was demonstrated.
