METHOD FOR CONTROLLING THE PHYSICAL PROPERTY OF NONLINEAR OPTIC MATERIAL KDPKH2PO4, Potasssium dihydrogen phosphate BY PROTON BEAM IRRADIATION TREATMENT AND NONLINEAR OPTIC MATERIAL KDP

摘要

in accordance with the present invention a non-linear optical materials (KH ₂ PO ₄ ) of the control method is a non-linear optical properties of materials prepared by the aqueous solution method KDP (KH ₂ PO ₄ ) is irradiated with a proton beam to the dielectric constant of the single crystal a ( ) is characterized in that which is changed . ; is a non-linear optical material so that physical properties of this control method and the formation of non-linear optical material according to the present invention is able to change the dielectric constant ( ) according to the value of the proton beam irradiation conditions and KDP KDP commercial When applied to the laser it is possible to adjust the light intensity of the second harmonic wave or the third harmonic wave .
