The semiconductor laser chip LDC includes an active layer 4, a pair of cladding layers 2 and 7 sandwiching the active layer 4, and a diffraction grating layer 6 which is optically connected to the active layer 4. The spatial light modulator SLM includes a common electrode 25, a plurality of pixel electrodes 21, and a liquid crystal layer LC arranged between the common electrode 25 and the pixel electrodes 21. A laser beam output in a thickness direction of the diffraction grating layer 6 is modulated and reflected by the spatial light modulator SLM and is output to the outside."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor laser device","description":"This semiconductor laser device includes a semiconductor laser chip and a spatial light modulator SLM which is optically connected to the semiconductor laser chip.
