Claim:
1. A laser device comprising: a plurality of semiconductor lasers; a driving device that supplies the driving electric current to said plurality of semiconductor lasers; a trigger generation circuit that sends a trigger signal for outputting said driving electric current to said driving device; a wave combining device that combines laser lights emitted respectively from said plurality of semiconductor lasers at the combined wave end; and a plurality of transmitting paths, further comprising: wherein at least one of said signal transmitting time, said electric current transmitting time and said light transmitting time is adjusted so that a total time of a signal transmitting time while said trigger signal transmits over said signal path, an electric current transmitting time while said driving electric current transmits over said electric current path, and a light transmitting time while said laser light transmits over said optical path can be the time set for respective plurality of said transmitting paths.
