Abstract
A visible light emitting element is mounted adjacent a lead-chalcogenide infrared diode laser element on the same supporting member or heat sink adjacent. The optical axis of the laser apparatus is adjusted using a visible light beam emitted by the visible light emitting element. The light source is then changed from the visible light emitting element to the infrared diode laser element by shifting the laser mount.
