Semiconductor light emitting device with stacked light emitting elements

A semiconductor light emitting device comprising:

• a supporting base;
• a first light emitting element provided on one face of the supporting base and comprising a first substrate and an electrode, wherein the first substrate is provided on a side of said first light emitting element facing away from said supporting base and the electrode is electrically connected to the first substrate;
• a second light emitting element stacked on the first light emitting element, wherein the second light emitting element comprises a second substrate, a first lasing portion and a second lasing portion, wherein the second substrate is provided on a side of the second light emitting element facing away from the supporting base;
• and wherein:
• the first lasing portion includes a first lasing lectrode electrically isolated from the first substrate;
• the second lasing portion includes a second electrode electricallly connected to the electrode;
• and
• the first substrate is transparent in the visible region.
