- a plurality of (three in this embodiment) beam splitters 18 correspond one-to-one with the telescope 16.
- the beam splitting elements 18 are arranged so as to face the corresponding output surfaces of the telescope 16.
- each beam splitting element 18 is a prism composed of three glass plates 19a, 19b, and 19c arranged 1J in the X direction. These three glass plates 19a and 19c have input surfaces arranged at different angles from each other. Each glass plate has an output surface parallel to its input surface. Each glass plate is placed between the input and output surfaces. It functions as an optical waveguide for transmitting light.
- These glass plates 19a and 19c receive the output beam 40 of the semiconductor laser array 28 from the telescope 16, and divide it into three along the horizontal direction (X direction). As shown in FIG.
- these three split beams have three optical paths branched from the optical path of the output beam 40 of the semiconductor laser array 28 on the YZ plane.
- the split beams 41 to 43 emitted from the beam splitter 18 are arranged in parallel along the Y direction and travel in parallel with each other.
- the field lens 20 is arranged such that its input surface 20a faces the output surfaces of all the beam splitting elements 18.
- the field lens 20 is a cylinder lens having a cylindrical surface extending along the Y-axis direction as an input surface 20a.
- the input surface 2 Oa of the field lens 20 is a cylindrical surface having a generatrix parallel to the Y-axis direction.
- This input surface 20a is close to the output surface of the beam splitter 18.
- the output surface 20b of the field lens 20 is a flat surface perpendicular to the Z-axis direction, that is, the direction of the optical axis 25.
- the input surface of field lens 20 has a sufficiently large area so that all split beams 41-43 generated by all beam splitting elements 18 are incident on field lens 20.
- the split beams 41 to 43 generated by the beam splitter 18 are condensed in a horizontal plane (ZX plane) by the field lens 20 as shown in FIG. Since the field lens 20 has no vertical focusing function, the split beams 41-43 are not focused in the vertical plane (YZ plane) as shown in FIG.
- the split beams 41 to 43 emitted from the field lens 20 enter the beam combining element 22.
- the beam combining element 22 has a configuration in which three prisms 29, three glass plates 30, and three prisms 31 are alternately stacked.
- the prism 29, the glass plate 30, and the prism 31 are in contact with each other. As shown in FIGS. 3 and 5, each prism and each glass plate receives one split beam.
- the prism 29, the glass plate 30, and the prism 31 have an input surface facing the output surface of the field lens 20 and an output surface parallel to the input surface.
- the input and output surfaces of prisms 29 and 31 are inclined at a constant angle with respect to the output surface of field lens 20. However, the inclination directions of the prisms 29 and 31 are opposite.
- the input surface and the output surface of the glass plate 30 are parallel to the output surface of the field lens 20.
- one prism 29, one glass plate 30, and one prism The partial element consisting of 31 sets the optical paths of these beams such that the three beams 41-43 split by one beam splitting element 18 overlap in the ZX plane.
- the glass plate 30 receives the central split beam 42 and propagates it without refraction. Due to the light condensing action of the field lens 20, the central beam 42 travels while converging along the Z direction.
- the input surfaces of prisms 29 and 31 receive split beams 41 and 43 on either side of the central beam and refract them toward central beam 42. As a result, the three split beams 41 to 43 are superimposed in the ZX plane.
- the output faces of prisms 29 and 31 deflect beams 41 and 43 in the opposite direction to the input face. This prevents the overlapped split beams 41-43 from being separated again. As a result, the divided beams 411-43 are combined into one beam 44 in the ZX plane.
- the prisms 29 and 31 and the glass plate 30 have no refracting action on the YZ plane. Therefore, in the YZ plane, a plurality of split beams 41 to 43 are arranged in parallel along the Y direction. Because the spacing between the split beams is small enough, these split beams form substantially one beam 44 in the YZ plane. In this way, the beam combining element 22 combines all the split beams into one beam 44.
- the beam splitter 18 splits the output beam 40 of the semiconductor laser array 28 into parallel beams 41-143.
- a divergent beam is also emitted from the output surfaces of the glass plates 19a-19c, which are optical waveguides. Since the output beams 40 of the semiconductor laser array 28 are collimated by the FAC 14 in the YZ plane, these beams are mainly diffused in the ZX plane and are substantially collimated in the YZ plane.
- the divergence angles of these beams are determined according to the divergence characteristics of the slow axis of the LD 38 and the characteristics of the telescope 16.
- FIGS. 2 and 4 show a beam 45 emitted from the central glass plate 19b as a representative of these diverging beams.
- the beam combining element 22 generates a combined beam 46 by superimposing the split beams 41-43 and the diverging beams.
- the diverging beam 45 has a sufficiently large width in the X direction than the beam 44 obtained by superimposing the divided beams 41-43.
- the width of the beam in the X direction is substantially equal to the width of the beam 45 in the X direction.
- the combined beam 46 is diffused along the optical axis 25 in the ZX plane, and travels in parallel with the optical axis 25 in the YZ plane. For this reason, the cross-sectional shape of the composite beam 46 gradually approaches a square.
- the condensing lens 24 receives the beam 46 synthesized by the beam synthesizing element 22 and condenses it along the optical axis 25.
- the condenser lens 24 is a lens system composed of a cylinder lens 32 and a plano-convex lens 34 arranged along the optical axis 25.
- the cylinder lens 32 has a flat surface perpendicular to the Z direction as an input surface, and has a cylindrical surface having a generatrix perpendicular to the X direction as an output surface.
- the plano-convex lens 34 has a convex surface as an input surface, and has a flat surface perpendicular to the direction as an output surface.
- the cylinder lens 32 and the plano-convex lens 34 focus the combined beam 46 in the ZX plane.
- the plano-convex lens 34 also condenses the combined beam 46 in the YZ plane. Thus, the diameter of the combined beam 46 is reduced while the cross-sectional shape of the combined beam 46 is kept square.
- the optical fiber 26 is aligned so as to have a common optical axis 25 with the condenser lens 24.
- the beam 46 condensed by the condenser lens 24 enters one end surface of the optical fiber 26 and propagates through the optical fiber 26.
- the laser beam emitted from the other end face of the optical fiber 26 is the output light of the laser device 10.
- the field lens 20 forms a pupil 36 behind the beam combining element 22 in the ZX plane (horizontal plane), more specifically, at the position of the front focal point 70 of the condenser lens 24.
- the front focal point 70 is located immediately before the condenser lens 24.
- the pupil 36 can be regarded as an exit pupil of an optical system arranged in front of the condenser lens 24.
- the laser array stack 12 and the field lens 20 are involved in forming the pupil 36 among the components of this optical system. Without field lens 20, pupil 36 would be at infinity. The higher the refractive power of the field lens 20, the closer the position of the pupil 36 is to the field lens 20.
- the pupil 36 By forming the pupil 36, it is possible to make a divergent beam emitted from the beam splitter 18 into a telecentric beam corresponding to the NA (numerical aperture) of the optical fiber 26. That is, the principal ray passing through the center of the pupil 36 travels behind the condenser lens 24 in parallel with the optical axis 25. As a result, many light beams enter the optical fiber 26 at an angle equal to or smaller than the acceptance angle of the optical fiber 26, so that the beam is efficiently guided to the optical fiber 26. Power S can. Accordingly, the laser device 10 can emit a high-power output beam from the optical fiber 26.
- the condenser lens can be simplified and downsized.
- the first position 72 is defined as the first position 72, which is forward from the front focal point 70 of the condenser lens 24 along the optical axis 25 by a distance twice as long as the focal length of the condenser lens, and is the condenser lens along the optical axis 25.
- a position advanced from the rear focal point 74 of the 24 by the focal length of the condenser lens to the rear side is defined as a second position 76.
- the field lens 20 preferably forms the pupil 36 between the first position 72 and the second position 76. If the pupil is formed in such a position range, the converging lens 24 can make the diverging beam from the beam splitter 18 sufficiently close to the telecentric beam, and thus obtain a sufficiently high coupling efficiency That can be S.
