The device in order to make coming out light firing from the laser illuminant which possesses the light ray formation device in order to make the cross section of the light ray form, and the cross section of depth extends long the optical fiber input

摘要

Being the light ray formation device in order light ray divided expedient possesses one which (2) and light ray deflection means (3,17) and light ray coupling means (2) it has light ray formation unit (1,16,22,23,24,25) at least, to form the cross section (4,6) of the light ray (5,7), as for the aforementioned light ray divided expedient (2), the light ray which hits to light ray formation unit (1,16,22,23,24,25) (5) it to be possible, as for light ray deflection means (3,17), to divide into two part light rays (8,9), it to be possible the part light ray (8,9) to direct one side at least to light ray coupling means (2) and to make deflect and light ray coupling means (2)From light ray formation unit (1,16,22,23,24,25) radiation is done the cross section of the light ray (7) which (6) in light ray formation unit (1,16,22,23,24,25) incidence is done the light ray which (5) with the cross section (4) in comparison in 1st direction (X) to become small, is vertical to this direction in the 2nd direction (Y and Z) which in order to become large, it is possible to make the both part light ray connect (8,9), in the light ray formation device whose, the aforementioned light ray coupling means (2) to be used as light ray divided expedient (2), just one side (8) of the part light ray, light ray deflection means (2,17Vis-a-vis being made to deflect) by, as for the other part light ray (9), light ray coupling means the light ray formation device which features that it hits to (2) directly.
