Abstract: The present invention provides a bonding method (S1) which is capable of achieving a high adhesive force without carrying out any special treatment on the second member (14), even in a case where the first member (11) has a surface on which a gold thin film (12) is formed. The first member (11) is made of a material other than gold and has a surface on which the gold thin film (12) is formed. The bonding method (S1) includes the steps of: (S11) irradiating, with laser light, at least part of a specific region (12a) of the surface of the first member (11), so that a base of the thin film (12) is exposed in the at least part of the specific region (12a); and (S12) bonding the second member (14) to the specific region (12a) by use of an adhesive (13).

Abstract: A double mirror (Mi) is made of a first mirror (Mi1) that is mounted on a top surface of a base plate (B) and a second mirror (Mi2) that is mounted on a top surface of the first mirror (Mi1). The first mirror (Mi1) has a reflective surface (S1) for reflecting an input beam. The second mirror (Mi2) has a reflective surface (S2) for reflecting the input beam which has been reflected by the reflective surface (S1).

Abstract: A double mirror (Mi) of a light-guiding device of the present invention is made of (i) a first mirror (Mi1) that is mounted on a top surface of a base plate (B) and has a reflective surface (S1) entering an input beam reflected by the reflective surface (S1) and (ii) a second mirror (Mi2) that is mounted on a top surface of the first mirror (Mi1) and is a prism having a reflective surface (S2) reflecting the input beam that has been reflected by the reflective surface (S1), the input beam reflected by the reflective surface (S2) being totally reflected inside the prism.

Abstract: A light-guiding device that converts an input beam bundle made of a plurality of laser beams that have respectively been emitted from a plurality of LD elements, to an output beam bundle made of a plurality of output beams, includes a plurality of double mirrors each corresponding to a corresponding one of the LD elements LDi, the double mirrors being separated from one another. The double mirrors Mi each are made of a first mirror Mi1 that is mounted on a top surface of a base plate B and a second mirror Mi2 that is mounted on a top surface the first mirror Mi1. The first mirror has a first reflective surface whose normal makes an angle of 45° with a normal of the top surface of the base plate. The second mirror has a second reflective surface whose normal makes an angle of 135° with the normal of the top surface of the base plate.
