Abstract:
A reflective laser activated remote phosphor (LARP) package comprising: a phosphor platelet oriented in a first plane defined by an x-y plane; a laser diode (LD) positioned to be offset along the x-axis from the phosphor platelet and above the first plane along a z-axis perpendicular to the x-y plane, the LD comprising: an output facet configured for emitting a laser beam (LB), the LB comprising: a slow axis oriented in a first direction along which the LB diverges at a first angle; and a fast axis oriented in a second direction along which the LB diverges at a second angle greater than the first angle; wherein the LD is oriented such that: the LB is bisected by the phosphor platelet such that the slow axis of the LB lies in an x-z plane and the fast axis of the LB is perpendicular to an x-z plane.
