Abstract
A pattern generatorproduces a predetermined pattern signalwhich is an electric signal, and a LD output lightof light signal is produced by inputting the pattern signalto a plurality of semiconductor lasers (LD)as a pump light source. To make a output lightto be a pulsed light not following a surge pulse rectangular, a fiber laser modulatoris configured that the pattern signalgenerated by a pattern generatorincludes four phases power level: low powered phase, power rising phase, high power phase and power decreasing phase.
