Abstract
Description
図1は実施の形態1に係るレーザ加工装置の構成図である。実施の形態1に係るレーザ加工装置100は、レーザビームを出射する複数の発振器1aから1eと、加工ヘッド301と、複数の伝送ファイバ101aから101eとを備える。図1では、右手系のXYZ座標において、複数の伝送ファイバ101aから101eが複数の発振器1aから1eから加工ヘッド301へ伸びる方向をX軸方向とし、X軸方向と直交する方向をY軸方向とし、X軸方向及びY軸方向の双方に直交する方向をZ軸方向とする。
図5は実施の形態2に係るレーザ加工装置の構成図である。実施の形態2に係るレーザ加工装置100Aでは、複数の発振器1のそれぞれの発振波長を変化させることにより、波長分散素子103上に重畳された出射ビーム12aから12eが、分岐ビーム22として特定の方向に分岐される。分岐ビーム22を用いることにより、加工対象物202の加工に適した特定のビーム形状が得られる。発振器1の発振波長を変化させる方法としては、図2に示す第1の構成例の場合には回折格子401の角度を調整すればよい。実施の形態2に係るレーザ加工装置では、波長分散素子103に入射するレーザビームの波長を変化させることにより、分岐ビーム22が得られる。
