    Abstract: The present invention relates generally to wavelength conversion devices and laser projection systems incorporating the same. According to one embodiment of the present invention, wavelength conversion devices are provided without limitation of their field of use to laser projection systems. For example, the wavelength conversion device may comprise an axial waveguide portion and a pair of lateral planar waveguide portions confined between a pair of relatively low index cladding layers. The effective index of refraction in the axial waveguide portion of the waveguide region and the effective index of refraction in the lateral planar waveguide portions of the waveguide region are established such that the relatively low intensity laterally distributed parasitic light is characterized by a scattering angle θ that is at least as large as the beam divergence angle of the relatively high intensity light propagating in the axial waveguide portion.

According to one embodiment of the present invention, wavelength conversion devices are provided without limitation of their field of use to laser projection systems. For example, the wavelength conversion device may comprise a waveguide region comprising a relatively linear waveguide portion and a pair of lateral planar waveguide portions. The output face of the wavelength conversion device comprises a multi-component output face comprising a core portion and a pair of lateral portions. The lateral portions of the output face are configured to be relatively non-transmissive and the waveguide region is structured such that an optical signal propagating along the waveguide region will define relatively low intensity laterally distributed parasitic light in substantial alignment with the lateral planar waveguide portions along the lateral, non-transmissive portions of the output face. Additional embodiments are disclosed and claimed.

    Abstract: A laser projection system is provided comprising a laser source, projection optics, scanning optics, and a scanning controller. The laser source comprises at least two punctual sources P1, P2 configured to generate two optical beams. The scanning controller is configured to drive the scanning optics to define a fast scanning axis direction in which lines of an image are projected and a slow scanning axis direction in which the optical beams address successive lines of the projected image. The position of the respective punctual sources relative to each other and to an optical axis of the projection optics provides an angular misalignment of the first and second optical beams downstream of the projection optics. The respective punctual sources are positioned such that the first and second optical beams are misaligned in the slow scanning axis direction to a greater extent than in the fast scanning axis direction.
