Fiber laser modulation method and modulator |
摘要 |
<p>A pattern generator 2 produces a predetermined pattern signal 11 which is an electric signal, and a LD output light 12 of light signal is produced by inputting the pattern signal 11 to a plurality of semiconductor lasers (LD) 3 as a pump light source. To make a output light 14 to be a pulsed light not following a surge pulse rectangular, a fiber laser modulator 1 is configured that the pattern signal 11 generated by a pattern generator 2 includes four phases power level: low powered phase, power rising phase, high power phase and power decreasing phase.</p> |
