摘要： According to one embodiment of the present invention, an optical package comprises one or more semiconductor lasers coupled to a wavelength conversion device with adaptive optics. The optical package also comprises a package controller programmed to operate the semiconductor laser and the adaptive optics based on modulated feedback control signals supplied to the wavelength selective section of the semiconductor laser and the adaptive optics. The wavelength control signal supplied to the wavelength selective section of the semiconductor laser may be adjusted based on the modulated wavelength feedback control signal such that the response parameter of the wavelength conversion device is optimized. Similarly, the position control signals supplied to the adaptive optics may be adjusted based on the modulated feedback position control signals such that the response parameter of the wavelength conversion device is optimized.

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： The present invention relates generally to semiconductor lasers and laser projection systems. According to one embodiment of the present invention, a method of correcting output power variations in a semiconductor laser is provided. According to the method, an output power feedback loop is utilized to generate optical intensity feedback signals representing actual output power of the laser source for discrete portions V1, Vi, Vj of the image signal. Error signals E1, Ei, Ej are generated representing the degree to which actual projected output power varies from a target projected output power for the discrete portions V1, Vi, Vj of the image signal. These error signals E1, Ei, Ej are utilized to apply corrected control signals G1', Gi', Gj' to the gain section of the semiconductor laser for projection of compatible discrete portions V1', Vi', Vj' of the image signal. According to another embodiment of the present invention, a system is provided for generating a projected laser image.
