Title:
WAVELENGTH CONVERSION DEVICE AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/137459
Kind Code:
A1
Abstract:
Disclosed is a wavelength conversion device, comprising: a light source which emits an excited light; a laser medium which employs the excited light in emitting a fundamental wave light; a resonator mirror which cooperates with the laser medium in forming a resonator with respect to the fundamental wave light; and a wavelength conversion element which wavelength converts the fundamental wave light into a harmonic light. The wavelength conversion element further comprises: a first end face which inclines by an angle θ with respect to a face which is orthogonal with respect to an optical axis of the resonator; and a second end face which is parallel with respect to the first end face.
