    摘要： A method and device for the nonlinear combination of laser light which produces a beam of uniform intensity, high spatial purity, and high conversion efficiency. The method includes emitting a laser light from a tunable distributed feedback fiber laser having both thermal and piezoelectric control elements which produces a laser light at a given frequency, wavelength, and intensity; converting the laser light in a nonlinear resonator which uses a nonlinear optical crystal for frequency conversion or mixing; and measuring the resonant frequency of the nonlinear resonator and adjusting the laser light frequency using both the thermal and piezoelectric elements of the fiber laser light source to match the resonant frequency conditions within the nonlinear resonator.

    摘要： A rapidly oscillating laser light source is produced that exhibits extended pulse duration having a substantially uniform amplified output. A pulsed beam of laser light having a given wavelength, frequency, duration and intensity is produced such that the pulse shape is controlled. The pulsed beam is amplified using a fiber amplifier which exhibits inherent changes in amplifier gain at the frequencies of interest. The fiber amplifier is continuously pumped. A feedback signal is provided with the amplified pulse characteristics and is used to adjust the pulse shape of the pulsed beam of laser light before amplifying, such that the intensity is changed over the pulse duration to generate a substantially uniform amplified output during each pulse.

    摘要： A microscopic optical structure controller for providing singular control of individual microscopic optical structures of a microelectromechanical optical device by a multiplexed stream of individual pixel values generated by a pixel value source. The microscopic optical structure controller includes at least one interconnect coupled to the pixel value source for receiving the multiplexed stream of individual pixel values and at least one mapper communicating with the interconnect for extracting individual pixel values from the multiplexed stream and applying the individual pixel values to one or more individual microscopic optical structures according to a configurable mapping. A method and a driver for providing singular control of individual microscopic optical structures of a microelectromechanical optical device are also disclosed.

    摘要： A display system able to reduce interpixel intensity gaps caused by the use of pulsed laser sources having relatively short optimum pulse duration. The interpixel intensity gaps are reduced by temporally offsetting multiple laser pulses for a display pixel during a corresponding pixel-scan period. The temporally offset pulses for the display pixel are then scanned to different locations on a viewing surface such that the display pixel has an improved intensity distribution. Additional reduction in the interpixel gaps may be accomplished by de-focusing the temporally offset pulses in a scan direction, increasing the duty cycle of the source lasers, and shifting the location of alternating frames on the viewing surface.
