20100272134 | Rapid Alignment Methods For Optical Packages - A method for aligning an optical package including a semiconductor laser operable to emit an output beam having a first wavelength, a wavelength conversion device operable to convert the output beam to a second wavelength and adaptive optics configured to optically couple the output beam into a waveguide portion of an input facet of the wavelength conversion device includes measuring a power of light having a first wavelength emitted by or scattered from the wavelength conversion device as the output beam is scanned over the input facet of the wavelength conversion device along a first scanning axis. A power of light emitted from the wavelength conversion device is then measured as the output beam is scanned over the input facet along a second scanning axis. A position of the second scanning axis relative to an edge of the wavelength conversion device is based on the measured power of light having the first wavelength. The output beam is then aligned with the waveguide portion of the input facet based on the measured power of light having the second wavelength. | 2010-10-28 |

20100272136 | LASER LIGHT SOURCE - The present invention relates to a laser light source having a structure for effectively suppressing generation of an optical surge upon a restart after suspension of output of pulsed light. The laser light source comprises a first light source outputting light with a first wavelength as pulsed light, a second light source outputting light with a second wavelength different from the first wavelength, an optical amplification fiber as an optical amplifier amplifying the pulsed light outputted from the first light source and the light outputted from the second light source, and a control unit controlling the output of the light from the second light source in accordance with the light output from the first light source. The first light source has an ON state in which repetitive output of the pulsed light on a fixed cycle starts and continues, and an OFF state in which the output of the pulsed light is suspended during a duration of not less than the fixed cycle. The control unit controls the second light source to output the light to the optical amplification fiber during the duration of the first light source being in the OFF state, so as to suppress a rise of population inversion of a rare earth element added in the optical amplification fiber. | 2010-10-28 |
