Abstract
Fiber Fabry-Perot Cavity laser phase plate for microscopy are described herein. In one aspect, a micro Fabry-Perot laser cavity for charged particle microscopy, can include: a first fiber assembly and a second fiber assembly, wherein each of the first fiber and the second fiber assembly includes: an entrance region including a single-mode fiber; a spacer region including a multimode fiber or a transparent substrate; a convergence region including a gradient index fiber or gradient index lens; and a speculum region including a multimode fiber or a transparent substrate, the entrance region, spacer region, the convergence region, and the speculum region being in optical communication with one another, and where a face of the speculum region of the first fiber assembly faces a face of the speculum region of the second fiber assembly, thereby defining a gap therebetween.
