摘要： A method for aligning a beam spot with a waveguide portion of a wavelength conversion device includes scanning a beam spot over the input face of the wavelength conversion device while measuring the output intensity of the device such that an output intensity for each of a plurality of fast scan lines is generated. A first alignment set point is then determined based on the output intensity of each fast scan line. A second scan of the beam spot is then performed over the fast scan line containing the first alignment set point while measuring the output intensity for each point along the fast scan line. A second alignment set point is then determined based on the output intensities measured during the second scan. The beam spot is then aligned with the waveguide portion using the first alignment set point and the second alignment set point.

摘要： Start-up methods for frequency converted light sources and projector systems comprising frequency converted light sources are described herein. The start-up methods generally comprise modulating the frequency converted light source over three degrees of freedom (two spatial dimensions and one wavelength dimension). Specifically, fast oscillation of an axis of an adjustable optical component is performed simultaneously with fast oscillation of a wavelength of the semiconductor laser while a second axis of the adjustable optical component is incrementally stepped and the output intensity of the frequency converted light source is monitored for each step. This start-up method allows for three linear searches to be used to rapidly locate the appropriate control settings for the frequency converted light source.

摘要： Methods of operating a frequency-converted laser source are disclosed. According to particular disclosed embodiments, a laser diode is driven in a pulsed mode to define pixel intensity values corresponding to desired gray scale values of image pixels in an image plane of the laser source. The pixel intensity values are a function of a laser control signal comprising a discontinuous pulse component, a relatively constant intensity component I, and a continuously variable intensity component I*. The pulse width w of the discontinuous pulse component is selected from a set of discrete available pulse widths according to a desired pixel gray scale value. A low-end pulse width w of the set of available pulse widths is established for a range of low-end pixel gray scale values and progressively larger pulse widths w are established for ranges of progressively higher pixel gray scale values. The relatively constant intensity component I makes a relatively insignificant contribution to pixel intensity at the low-end pulse width w for the range of low-end pixel gray scale values and assumes a non-zero value for enhanced conversion efficiency at the progressively larger pulse widths w established for the higher pixel gray scale values. The continuously variable intensity component I* varies according to the desired gray scale value of the selected pixel and the contributions of the relatively constant intensity component I and the pulse width w to pixel intensity.
