摘要： 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.

摘要： Methods of controlling semiconductor lasers are provided where the semiconductor laser generates a wavelength-modulated output beam λ MOD that is directed towards the input face of a wavelength conversion device. The intensity of a wavelength-converted output λ CONV of the device is monitored as the output beam of the laser is modulated and as the position of the modulated output beam λ MOD on the input face of the wavelength conversion device is varied. A maximum value of the monitored intensity is correlated with optimum coordinates representing the position of the modulated output beam λ MOD on the input face of the wavelength conversion device. The optical package is operated in the data projection mode by directing an intensity-modulated laser beam from the semiconductor laser to the wavelength conversion device using the optimum positional coordinates. Additional embodiments are disclosed and claimed. Laser controllers and projections systems are also provided.
