各種非線形結晶の品質レベルと特徴 (下表） 結晶の選択を間違わないように
−−ＬＢＯ・ＢＢＯ・ＫＴＰ結晶は別格の品質−− −−α（吸収）が大→結晶欠陥多く（致命的）−−
◆高品質の波長変換には、ＬＢＯ・ＢＢＯ・ＫＴＰ結晶（α：１０−６）に限る
◆ハイパワーの波長変換には、ＬＢＯ・ＢＢＯ・ＫＴＰ結晶（α：１０−６）に限る
◆ＳＬＮ・ＳＬＴ結晶等は（ＬＢＯ・ＢＢＯ・ＫＴＰ結晶と比較で）粗悪品質
◆ＧＲＩＩＲＡ(Green Induced IR Absorption)はほとんどの結晶にある

日本で使われている一般的なパラメータ値と大きく食い違う。 例： BBO Dｅｆｆ １．３２ ｐｍ/V, CLBO Dｅｆｆ ０．８４ ｐｍ/V
**新非線形結晶・ＢｉＢＯ結晶は
「Ｄｅｆｆ値」 において、他のボレート系非線形結晶と比較して、抜群に優れている。 大きな可能性を秘めた結晶。
LBO結晶でType-I
SHGでNCPM（Non-critical Phase Matching）があり、変換効率が特に優れている。
スーパー品質 BBO・LBO結晶 詳しくは個々にご相談下さい。
