Summary: | To suppress variation in energy amount, in which electric currents supplied to a laser emission element 41 are integrated, due to ripple of electric current supplied to the laser emission element 41 connected to an output part 454.SOLUTION: An output control device 460, which controls electric current supplied to a laser emission element 41 connected to an output part 454, comprises an emission control part 455 which controls start and stop of electric current supplied to the laser emission element 41, and a control part 46 which controls the emission control part 455. The control part 46 stops electric current supply to the laser emission element 41 by the emission control part 455 on the basis of an energy amount in which electric currents, which have flown to the laser emission element 41 from start of electric current supply to the laser emission element 41 by the emission control part 455, are integrated.SELECTED DRAWING: Figure 10
【課題】出力部454に接続されたレーザー発光素子41に供給する電流のリップルに起因するレーザー発光素子41に供給する電流を積算したエネルギー量のばらつきを抑制することを目的とする。【解決手段】出力部454に接続されたレーザー発光素子41へ供給する電流を制御する出力制御装置460であって、レーザー発光素子41への電流供給の開始と停止とを制御する発光制御部455と、発光制御部455を制御する制御部46と、を備え、制御部46は、発光制御部455によりレーザー発光素子41への電流供給を開始してからレーザー発光素子41へ流れた電流を積算したエネルギー量に基づいて、発光制御部455によるレーザー発光素子41への電流供給を停止する。【選択図】図10 |
