PURPOSE:To amplify a light in high sensitivity and high resolution with low voltage and low power consumption by emitting information light which contains image information in a laser array and inducing a laser oscillation in the individual laser media in accordance with the image information. CONSTITUTION:Information light 10 which contains image information is incident through an infrared filter 9, and focused on a laser rod array via a lens array. The individual laser rods 1 which form this laser rod array are excited by an exciting light from a Kr arc lamp 7, and a laser oscillation occurs in accordance with the image information by the emission of the information light. The light which contains the image information amplified by the induction and the emission is outputted from the laser rod array, and converted into an electric signal via an image pickup element 6. In this case, an LED or the like may be used instead of the lamp 7 as an exciting light source. In this manner, a light amplifier which has high sensitivity and high resolution can be obtained. |
