摘要： An RGB light source that uses an optical fiber laser to generate a near-infrared (NIR) output light beam, and a wavelength conversion system that receives the output NIR light beam and forms therefrom red, green and blue light beams. The fiber laser includes multiple stages, wherein the first stage includes a solid-state laser to generate an initial NIR light beam. One or more subsequent stages operate to amplify the NIR light beam to form a relatively high-average-power output NIR light beam. Only light from the fiber laser is used to generate the red, green and blue-wavelength output light beams. The wavelength conversion system includes three or fewer non-linear optical (NLO) units. A color display that utilizes the RGB light source is also disclosed.

摘要： The present invention relates generally to semiconductor lasers and laser projection systems. According to one embodiment of the present invention, a projected laser image is generated utilizing an output beam of the semiconductor laser. A gain current control signal is generated by a laser feedback loop to control the gain section of the semiconductor laser. Wavelength fluctuations of the semiconductor laser are narrowed by incorporating a wavelength recovery operation in a drive current of the semiconductor laser and by initiating the wavelength recovery operations as a function of the gain current control signal or an optical intensity error signal. Additional embodiments are disclosed and claimed.

摘要： A laser projection system is provided comprising a light source, a phase retarding element, and a beam scanning element. The light source comprises at least one frequency-converted laser source comprising a wavelength-tunable laser diode and a wavelength conversion device. The phase retarding element is configured to resolve the polarization of a frequency-converted laser beam into two orthogonal linearly polarized components such that one component of polarization is phase delayed relative to the other. Frequency-converted laser beam polarization in the 2D image frame is a function of the degree to which the respective components of polarization are delayed relative to each other and varies with wavelength variations in the output of the wavelength-tunable laser diode. Polarization variations of the frequency-converted laser beam in the 2D image frame are sufficient to scramble image speckle patterns across the 2D image frame. In another embodiment of the present disclosure a laser projection system is provided where the system comprises a wavelength-tunable laser diode comprising a phase control section. The laser projection system is programmed to apply a dither signal to the phase control section and the dither signal introduces wavelength variations in the output of the wavelength-tunable laser diode. The wavelength variations in the output of the wavelength-tunable laser diode reside within a FWHM conversion bandwidth of the wavelength conversion device and are at a rate that is sufficient to scramble pixel-specific polarizations and image speckle patterns across the 2D image frame. Methods of operating laser projection systems are also provided.
