Description
２次元の発光素子アレイから射出された光を集光することで高出力レーザーとして用いることが可能であり、特許文献１に開示されているようにレーザー点火プラグの光源として用いられる光源デバイスが知られている。
このような光源デバイスをレーザー点火プラグとして用いるためには、２次元の発光素子アレイからの光を効率良く且つ小スポット状に集光しなければならない。そのためには２次元の発光素子アレイからの放射光を一度コリメートしてから集光することが有効である。
この場合、発光素子ごとにコリメートしなければならないため、コリメートレンズは発光素子に近接した位置に設置しなければならない。このため、２次元のレンズアレイを２次元の発光素子アレイ上に設けることが最も有効である。
The light emitted from the two-dimensional light emitting element array it is possible to use as a high power laser by collecting light, a light source device that is used as a light source of les Za spark plugs as disclosed in Patent Document 1 Is known .
In order to use such a light source device as a laser spark plug, the light from the two-dimensional light emitting element array must be collected efficiently in a small spot shape. For this purpose, it is effective to collimate the radiated light from the two-dimensional light emitting element array once and then collect it.
In this case, since it is necessary to collimate each light emitting element, the collimating lens must be installed at a position close to the light emitting element. For this reason, it is most effective to provide a two-dimensional lens array on the two-dimensional light emitting element array.
