[摘要]：We present an efficient laser welding assembling sequence for minimizing the misalignment from the postweld shift in butterfly packages during fiber-to-semiconductor laser coupling. The misalignment from the postweld shift that arises during the welding of a nickel clip and metal ferrule can be compensated by an optimal initial shift prior to Nd:YAG laser welding and by a mechanical adjustment prior to the laser hammering process. As a result, the number of laser hammering sequences required to compensate for misalignment are significantly reduced. (C) 2010 Society of Photo-Optical Instrumentation Engineers.
