Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a hollow-core optical-fiber filter to enable an optical beam output from a laser to have a narrow linewidth and low frequency noise fluctuations.SOLUTION: A hollow-core optical-fiber filter 100 includes a hollow-core optical fiber 110 having a first end-face 112 and an opposing second end-face 114. The hollow-core optical-fiber filter 100 also includes a first reflective end-cap 40 positioned at the first end-face 112 and a second reflective end-cap 41 positioned at the second end-face 114.
