Abstract

Methods of controlling semiconductor lasers are provided where the semiconductor laser generates a wavelength-modulated output beam λthat is directed towards the input face of a wavelength conversion device. The intensity of a wavelength-converted output λof the device is monitored as the output beam of the laser is modulated and as the position of the modulated output beam λon 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 λon 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.
