Summary: We designed, fabricated, and characterized the first hollow core double-clad fiber coupler for nonlinear micro-endoscopy. The coupler consists of a pure silica negative curvature hollow core double-clad fiber and a highly multimode fiber fused together. The use of a low fusion temperature soft (borosilicate) glass multimode fiber enabled the fabrication of this coupler without altering the geometry of the negative curvature fiber. A power transfer of 60% from the double-clad fiber to the multimode fiber was measured at 500 nm. The applicability of the coupler was demonstrated through two-photon fluorescence and second harmonic generation imaging of unlabeled biological tissues using an endoscopic head mounted on the hollow core double-clad fiber coupler. This device greatly simplifies the integration of nonlinear micro-endoscopes based on hollow core double clad fibers.
