Abstract
A light source includes a light emitting element configured to emit a non-diffraction limited input light beam, a nonlinear frequency conversion (NLFC) component that exhibits walkoff and performs second harmonic generation whereby at least a portion of an output beam outputted by the NLFC component has twice a frequency of the input beam, and an optical component positioned to receive the input light beam and configured to converge the non-diffraction limited input beam into the NLFC component. The light emitting element emits the input light beam having a beam quality factor in at least one plane of the input beam that is greater than 2 (M>2). Furthermore, the light emitting element is a laser diode including AlInGaN (0≦x≦1, 0≦y≦1) semiconductor materials, and one dimension of an emission region of the laser diode is at least 5 μm.
