Description
Claims (1)
- レーザ光を出射する複数のレーザ発光部と、
前記レーザ発光部から出射されるレーザ光が入射される光学系と、
前記光学系から出射されるレーザ光が入射される導光体と、を備え、
前記導光体は、長尺な平板状に形成されて且つ厚み方向で重なるように配置される複数の導光板と、前記導光板の間に配置され、所定の導光板に入射された光が隣接する導光板に向けて透過することを防止すべく、前記導光板よりも低い屈折率である透過防止部と、を備え、
前記光学系は、前記導光板の厚み方向において、出射する光の焦点位置が前記導光板の幅方向の端面となるように、集光すると共に、所定の導光板に入射された光が隣接する導光板に向けて透過することを防止すべく、前記導光板に入射した後に前記透過防止部に入射する光が臨界角よりも大きい角度で入射し続けるように、集光し、
前記各導光板は、前記幅方向の端面から入射される光を長手方向の端部に向けて反射させる反射部を備えるレーザ光源装置。
