Abstract
Start-up methods for frequency converted light sources and projector systems comprising frequency converted light sources are described herein. The start-up methods generally comprise modulating the frequency converted light source over three degrees of freedom (two spatial dimensions and one wavelength dimension). Specifically, fast oscillation of an axis of an adjustable optical component is performed simultaneously with fast oscillation of a wavelength of the semiconductor laser while a second axis of the adjustable optical component is incrementally stepped and the output intensity of the frequency converted light source is monitored for each step. This start-up method allows for three linear searches to be used to rapidly locate the appropriate control settings for the frequency converted light source.
