| 英文摘要 | PURPOSE:To obtain an output signal having high S/N ratio from a light amplifier by coupling semiconductor lasers having different oscillation outputs on a light irradiating line and sequentially coupling between the respective semiconductor lasers to input signal. CONSTITUTION:A semiconductor laser (LD) 11 of the first stage is in oscillated state, and is moved slightly in the oscillated state toward an increase in the output by the coupling effect of an input light signal inputted from a fiber 2. An LD 12 of the second stage is turned on due to the increase in the oscillation due to the coupling effect of the LD 11 of the first stage to start oscillation. Although an LD 13 of the third stage is set in oscillated state, when the LD 12 of the second stage starts oscillating, it transfers its oscillating state so as to transmit the light signal due to only the delay of the coupling time. |
