Abstract:
1. An optical package comprising a semiconductor laser, a wavelength conversion device, a lens assembly, and one or more adjustable optical components, wherein: the lens assembly and the adjustable optical component are configured to direct an output beam of the semiconductor laser towards the input face of the wavelength conversion device and to vary the position of the output beam on the input face of the wavelength conversion device; and the lens assembly and the adjustable optical component are further configured to define a folded optical path such that laser light propagating along the optical path from the semiconductor laser to the wavelength conversion device is first collimated or nearly collimated by the lens assembly prior to being reflected by the adjustable optical component and is focused by the same lens assembly on the input face of the wavelength conversion device after being reflected by the adjustable optical component.
