英文摘要	A heat-reduced package of an optical fiber head comprising a delivery optical fiber (DOF), a cladding mode stripper, an optical end cap, a beam shaper, a window, and a housing operates for delivering the laser light from DOF to free space with a uniform temperature gradient inside the housing while maintaining beam quality. The cladding mode stripper comprising a section of cladding-exposed DOF inside bore of the glass ferrule fused together is effective to remove cladding modes from DOF. The optical end cap comprising a corrugated structure is configured to deflect the cladding modes, reduce optical feedback, and facilitate optical and thermal dispersion. The housing comprises another corrugated structure on an inner wall to absorb undesired optical energy. The housing may further comprise a cooling slot to disperse the heat accumulated in the housing to its surroundings.
