Abstract:
1. A method of controlling an optical package comprising a semiconductor laser, a wavelength conversion device, one or more adjustable optical components configured to optically couple the output of the semiconductor laser with an input face of the wavelength conversion device, and an intensity sensor configured to monitor intensity variations of a wavelength-converted output λ CONV of the wavelength conversion device, the method comprising: operating the semiconductor laser to generate a wavelength-modulated output beam λ directing the modulated output beam λ operating the adjustable optical components to vary the position of the modulated output beam λ monitoring the intensity variations of a wavelength-converted output λ correlating a maximum value of the monitored intensity variations of the wavelength-converted output λ terminating the variation of the position of the modulated output beam λ operating the optical package in a data projection mode by directing an intensity-modulated laser beam from the semiconductor laser to the wavelength conversion device using the optimum positional coordinates for the adjustable optical components.
