英文摘要	PURPOSE:To improve the focussing intensity enabling to project the sharp and parallel beams by a method wherein the focussing lens is arranged near the semiconductor laser element enabling to adjust the location of the lens. CONSTITUTION:The focussing lens 7 provided with the permanent magnets MX, MY and MZ between the semiconductor element 3 arranged on the cooling substrate 2 and the transparent window 6 is arranged enabling to adjust the location and the electromagnets EMX, EMY and EMZ working on said permanent magnets to adjust the location of the lens 7 are arranged on the outside of vacuum airtight container 5. Then the light radiated from the semiconductor laser element 3 adjusting the location of the focussing lens 7 by means of controlling the exciting current of each electromagnet is projected outside through the transparent window 6 as the parallel beams. Especially the focussing intensity of the light may be improved by means of arranging the foccussing lens 7 very near the semiconductor laser element enabling to adjust the location of the lens 7.
