<P>PROBLEM TO BE SOLVED: To contribute to miniaturization of a laser device. <P>SOLUTION: The laser device includes a beam splitter that splits laser light into two lines, a second transparent member, and a hollow member arranged between the beam splitter and the second transparent member. The beam splitter has a reflection film on a surface facing the hollow member, while having a first junction film on the reflection film. The second transparent member has a reflection film on a surface facing the hollow member, while having a second junction film on the reflection film. The hollow member has a third junction film on a surface around an opening of the hollow part and facing the beam splitter and on a surface facing the second transparent member. The first junction film of the beam splitter and the third junction film of the hollow member are joined by atomic diffusion joining. The second junction film of the second transparent member and the third junction film of the hollow member are joined by atomic diffusion joining. <P>COPYRIGHT: (C)2012,JPO&INPIT |
