Beschreibung
Zusammenfassung:	A laser apparatus includes a semiconductor laser, an optical resonater and a wavelength coverter made of a nonlinear optical material. The nonlinear optical material has at least one of aromatic ring and metal ion, and wherein at least one element selected from the group consisting of ion bonding hydrogen, hydrogen bonding hydrogen and hydrogen of water of crystallization is replaced with deuterium. The nonlinear optical material is formed by removing water of crystallization from an organic ionic crystal containing at least one of aromatic ring and metal ion, and recrystallizing with a solvent comprising at least one of ionic bonding deuterium, hydrogen bonding deuterium, and heavy water.
