Abstract

See full text

A display light source (230) includes a gain media (232), an output reflector (246), and a wavelength converter (244) that cooperate to generate a source output beam (260). The gain media (232) generates a media output beam (247) that exits an output facet (232B) of the gain media (232). The media output beam (247) has a first spectral frequency range and a relatively large number of modes. The output reflector (246) is spaced apart from the gain media (232), and the output reflector (246) forms a portion of a laser cavity (251). The wavelength converter (244) is positioned within the laser cavity (251). The wavelength converter (244) converts at least a portion of the media output beam (247) from the first spectral frequency range to a converted beam (258) having at a secondary spectral frequency range. For example, the wavelength converter (244) can double the frequency of the media output beam (247). Additionally, the light source (230) can include a wavelength controller (238) that controls the number of modes that are lasing in the laser cavity (251), and that controls the spectral width and the center wavelength of the light that is lasing in the laser cavity (251)
