Claim:
An optical package comprising a semiconductor laser, a wavelength conversion device, a lens assembly, and an adjustable minor, wherein: the wavelength conversion device comprises a waveguide portion; the semiconductor laser, the adjustable mirror and the wavelength conversion device are oriented to form a folded optical pathway between an output of the semiconductor laser and an input of the wavelength conversion device such that a beam of the semiconductor laser is directed through the lens assembly and onto the adjustable mirror and reflected by the adjustable mirror back through the lens assembly and onto the waveguide portion of the wavelength conversion device; the adjustable mirror comprises a singular flexure pivot about which the adjustable minor is cylindrically deformed thereby altering a radius of curvature of the adjustable mirror and adjusting the focal length of the adjustable mirror such that the beam of the semiconductor laser may be focused on the waveguide portion of the wavelength conversion device; the beam of the semiconductor laser has a major axis of divergence and a minor axis of divergence and the semiconductor laser is positioned such that the minor axis of divergence is parallel to the pivot axis of the singular flexure pivot; the optical package is programmed such that the beam of the semiconductor laser has a fast axis and a slow axis and the slow axis of the beam is parallel to the singular flexure pivot of the adjustable mirror; the adjustable mirror comprises a first mirror region and a second minor region positioned on opposite sides of the singular flexure pivot, a first positioning actuator is positioned to apply a first force to the first minor region of the adjustable mirror, a second positioning actuator is positioned to apply a second force to the second mirror region of the adjustable mirror, and the optical package is programmed such that the first and second forces act in the same direction; the optical package is further programmed to control the deformation of the adjustable mirror and a tilt of the adjustable mirror about the pivot axis of the singular flexure pivot by controlling a magnitude and direction of the first force applied to the first mirror region by the first positioning actuator and a magnitude and direction of the second force applied to the second mirror region by the second positioning actuator; and the angular orientation of the adjustable mirror may be adjusted such that the beam of the semiconductor laser may be positioned along two directions on the waveguide portion of the wavelength conversion device.
