## Abstract A thermally expanded core fiber with high numerical aperture (HNAβTEC) is demonstrated here to relax the tolerance of laser diode (LD) to fiber alignment. We experimentally clarify the dependence of mode field radius (MFR) on heating time for HNAβTEC fiber. The MFR was expanded at the i
