Abstract: Compact laser systems are disclosed which include ultrafast laser sources in combination with nonlinear crystals or waveguides. In some implementations fiber based mid-IR sources producing very short pulses and/or mid-IR sources based on a mode locked fiber lasers are utilized. Some embodiments may include an infrared source with an amplifier system comprising, in combination, a Tm fiber amplifier and an Er fiber amplifier. A difference frequency generator receives outputs from the Er and/or Tm amplifier system, and generates an output comprising a difference frequency. Exemplary applications of the compact, high brightness mid-IR light sources include medical applications, spectroscopy, ranging, sensing and metrology.

Abstract: Woven material comprises a first set of electrically conductive elements and a second set of hollow fibres, the hollow fibres containing electrophoretic material. The electrically conductive elements may be substantially perpendicular to the hollow fibres. A third set may also be present, for example, a set of insulated electrically conductive elements (as shown in Figure 1), substantially parallel to the hollow fibres, or a set of electrically conductive elements, being contained within the hollow fibres, or another set of hollow fibres, also containing electrophoretic material, being substantially perpendicular to the original hollow fibres. A display device comprising the woven material is also described which further includes electrical connectors connecting to the electrically conductive elements and circuitry connected to the electrical connectors and driving the display device.

Abstract: In a single path multimedia projector (30), the light emitted from blue, green, and red generally monochromatic LEDs (72) is propagated through optical fibers (76) and then integrated through an optical integrator (40). A display controller (56) receives image data from a personal computer (58) and converts the data to color frame sequential data delivered to a common display device (44). The controller (56) synchronizes the data with ON/OFF signals conveyed to an LED power supply (34). The electronically synchronized frame sequential information is cycled faster and more accurately than achievable with a color wheel system (10). In a multiple path projector (120), the light from LEDs (72) can be ON continuously, propagated along separate optical paths (36), and integrated through an integrator (40). The color frame sequential data is delivered to controller-synchronized, separate display devices (44). The output is coupled into a combiner (122) to form a composite image.

Abstract: The present invention is a method of processing an optical signal, including the steps of (a) inputting signal light into a first nonlinear optical medium to broaden the spectrum of the signal light through self phase modulation occurring in the first nonlinear optical medium, thereby obtaining first spectrally broadened light (supercontinuum light), (b) compensating for chromatic dispersion effected on the first spectrally broadened light obtained in the step (a), and (c) inputting the first spectrally broadened light processed by the step (b) into a second nonlinear optical medium to broaden the spectrum of the first spectrally broadened light through self phase modulation occurring in the second nonlinear optical medium, thereby obtaining second spectrally broadened light.
