Zusammenfassung:A semiconductor-laser-chip-on-submount includes: a semiconductor laser chip that includes a semiconductor portion having an emitting facet and a rear facet along a longitudinal direction and emits laser light from the emitting facet; and a submount where the semiconductor laser chip is mounted. Further, a first distance between the submount and the emitting facet of the semiconductor portion is less than a second distance between the submount and the rear facet of the semiconductor portion.
