Abstract
A wavelength conversion device that includes a plurality of crystal layers adjacent to one another such that crystal-axis orientations thereof are alternately arranged, the plurality of crystal layers each including a first-thickness portion having a first thickness and a second-thickness portion having a second thickness smaller than the first thickness; and an adhesive layer in at least part of a gap between adjacent second-thickness portions of the plurality of crystal layers and with which the plurality of crystal layers are bonded to one another.
Claims19
A wavelength conversion device comprising:
- a plurality of crystal layers adjacent to one another such that crystal-axis orientations of the crystal layers alternate between adjacent crystal layers, the plurality of crystal layers each including a first-thickness portion having a first thickness and a second-thickness portion having a second thickness smaller than the first thickness;
- and
- an adhesive layer in at least part of a gap between adjacent second-thickness portions of the second-thickness portions of the plurality of crystal layers and with which the plurality of crystal layers are bonded to one another,
- wherein the first thickness portions are in direct contact with each other in a thickness direction of the plurality of crystal layers.
A method of manufacturing a wavelength conversion device, the method comprising:
- providing a plurality of crystal layers each including a first-thickness portion having a first thickness, a second-thickness portion having a second thickness smaller than the first thickness, and a crystal-axis orientation;
- placing adhesive over at least part of the second-thickness portion of a first crystal layer of the plurality of crystal layers;
- placing a second crystal layer of the plurality of crystal layers adjacent the first crystal layer such that the respective first-thickness portions and the second-thickness portions of the first and second crystal layers are adjacent each other, the crystal-axis orientations of the first and second crystal layers are alternately arranged, and the respective first thickness portions of the first and second crystal layers are in direct contact with each other in a thickness direction of the plurality of crystal layers;
- and
- bonding the plurality of crystal layers to one another with the adhesive.
