Abstract: PURPOSE:To realize a low cost and miniaturization of an optical repeater, by branching the output of a semiconductor laser light amplifier to convert it into an electric signal and then controlling the intensity of an optical signal delivered from a laser medium with said electric signal to give an AGC function to an optical amplifier. CONSTITUTION:An optical signal supplied to a laser medium 1 is amplified by the medium 1, and this amplified optical signal is delivered via a Y branching circuit 2. In this case, some beams are branched by the circuit 2. These branched beams are received by a pin photodiode 3 and then converted into electric signals proportional to the light intensity to be supplied to a gain control circuit 4. The circuit 4 supplies a DC current to the medium 1 in proportion to the intensity of the light which amplified the input electric signal. If the level of the output signal of the medium 1 is high, the current supplied to the medium 1 is increased by the output of the circuit 4. Then the amplification factor is reduced, and the gain is automatically controlled.

Abstract: PURPOSE:To reduce the effect of the erasing energy to record/reproduction and to erase and record signals at a time, by forming an erasing spot having the major axis of oblong shape to the relative shift direction and providing a maximum light intensity part at the head of the shift direction. CONSTITUTION:A diffraction element 118 gives a diffraction effect to an incident light beam (m) toward a guide groove 51 on a disk to change the intensity distribution of an erasing light spot M on the groove 51. When a point X on an optical recording medium enters the spot M, the temperature is suddenly increased at a high intensity area of the head part of the spot M. Then the temperature reaches a level near a fusing point and then drops less than the fusing point at a point where the light power starts its reduction. Thus the temperature is gradually lowered and a thin film is cooled down gradually for a period of time needed for crystallization for erasion of recorded signals. Then the recording light L of a semiconductor laser 101 is irradiated to the point X for record of new signals.
