Title:
NONLINEAR OPTICAL LASER ELEMENT
Document Type and Number:
Japanese Patent JP2570497
Kind Code:
B2
Abstract:
PURPOSE: To reduce the size of a device and curtail the processes of the alignment between elements, by performing a laser oscillation and a wavelength conversion through one element.
CONSTITUTION: By the single crystal of α-BaB2O4 itself, any laser oscillation and any wavelength conversion are impossible, but by the doping of a laser activating element, its laser oscillation is made possible. On the other hand, β-BaB2O4 is a nonlinear optical material whereby any laser oscillation is not possible, but a wavelength conversion is possible. Therefore, the single crystal of α-BaB2O4 is so made to be one with β-BaB2O4 that the orientation wherein the phase matching of β-BaB2O4 with the oscillation light emitted from α-BaB2O4 is made possible can be obtained. Thereby, the nonlinear optical laser element wherein the laser oscillation and wavelength conversion can be performed concurrently by one element can be realized.
