Spontaneous emission laser beams are outputted using optical amplifiers (12a, 12b) each having an input end terminated without reflection and passed, respectively, through band-pass filters (13a, 13b) to produce band-pass filtered spectrum slice beams, which are multiplexed to produce a modulation beam as a dummy beam. |
