摘要： In an up-conversion laser using Tm, blue light having a wavelength of 450 nm and blue light having a wavelength of 480 nm are outputted simultaneously. A high output is enabled with a high efficiency, and a green up-conversion laser is also realized by a similar means. A hybrid fiber laser apparatus includes a light source which outputs light near a wavelength A, and comprises a means for reflecting light near the wavelength A, which is provided at another end of the optical fiber, thereby to form an optical resonator for the wavelength A. In this hybrid fiber laser apparatus, an up-conversion fiber is provided in the optical resonator for the wavelength A, and optical resonator structures for a wavelength B constructed by reflection means and for a wavelength B are respectively provided at two positions at both ends of the up-conversion fiber. Of the two reflection means, the reflection means in the laser diode chip side is arranged so as to achieve high reflection, and the other reflection means in the other end side is arranged so as to achieve partial reflection, thereby to obtain output light having a wavelength B from the partial reflection side.

摘要： According to one embodiments a video signal control apparatus includes an average luminance detector and a display luminance controller. The average luminance detector detects the average luminance of a video signal with respect to each frame. The display luminance controller controls the display luminance of a first frame using the average luminance of a second frame prior to the first frame. When luminance change from the average luminance of the first frame to that of the second frame exceeds a predetermined threshold, the display luminance controller replaces the average luminance of the second frame with that of the first frame to control the display luminance of the first frame based on the average luminance of the first frame.
