ABSTRACT:
Two etalons in series may be angled to reduce parasitic reflections in the space between the two. The etalons may be soldered on either side of a post having an aperture there through to allow light to pass. Various sized solder balls and/or solder pads may be used to create the desired angle and to secure the etalons to the post. Alternatively, a lip on the post may create the desired angle. Once secured to the post, rather than aligning the etalons by pick and place methods individually, the post and attached etalons may be secured as a single unit to an optical system, such as within the cavity of an external cavity diode laser (ECDL).
