Abstract
Semiconductor laser assemblyis provided with semiconductor laser deviceand heat dissipation member. Semiconductor laser deviceincludes semiconductor laser element, lead-frame, lower and upper enclosuresandand plate-like springconnected to lead-frame. Semiconductor laser elementis mounted on lead-framethrough sub-mounting member. Lower and upper enclosuresandhave an opening through which laser beams from semiconductor laser elementare emitted. Plate-like springis connected to lead-frameand has wing and holding portionsand. Holding portionis a C-character in cross section to put lower and upper enclosuresandtogether. Heat dissipation memberhas inside walls to define perforation, so that wing portionsof plate-like springpushes semiconductor laser deviceagainst the inside walls of heat dissipation memberwhen the semiconductor laser deviceis set in perforation
