Patent ID: 7751045

Claim:
A method for aligning an optical package comprising a laser, a wavelength conversion device, and at least one adjustable optical component, the method comprising: directing a beam spot of the laser on an input face of the wavelength conversion device using the adjustable optical component; measuring an output intensity of the wavelength conversion device; performing a first scan of the beam spot across the input face of the wavelength conversion device by oscillating the adjustable optical component about a first scanning axis at an approximate resonant frequency of a drive mechanism of the adjustable optical component; stepping the scan of the beam spot along an orthogonal scan line to generate a plurality of output intensities for a plurality of fast scan lines across the input face of the wavelength conversion device; determining a first alignment set point along the orthogonal scan line based on the plurality of output intensities for the plurality of fast scan lines; performing a second scan of the beam spot across the input face of the wavelength conversion device along a fast scan line containing the first alignment set point to generate an output intensity for points along the second scan, wherein the second scan is performed by oscillating the adjustable optical component about the first scanning axis at an approximate resonant frequency of the drive mechanism of the adjustable optical component; determining a second alignment set point along the second scan based on the output intensities generated during the second scan, wherein the first alignment set point and the second alignment set point define a position where the beam spot is aligned with the waveguide portion of the wavelength conversion device; and positioning the beam spot on the waveguide portion of the wavelength conversion device using the first alignment set point and the second alignment set point.
