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 the intensity of a wavelength-converted output λ CONV of the wavelength conversion device, the method comprising: directing an output beam of the semiconductor laser towards the input face of the wavelength conversion device; transitioning operation of the optical package to a shuttered or partially shuttered operational mode by operating the adjustable optical components to vary the position of the output beam on the input face of the wavelength conversion device while monitoring the intensity of a wavelength-converted output λ terminating the variation of the position of the output beam on the input face of the wavelength conversion device when the monitored intensity of the wavelength-converted output λ
