▎ 摘　　要

NOVELTY - The laser has a lower electrode (10), an N-type substrate (2), an N-type distribution Bragg reflector (31), an active layer (4), a current limiting layer (5), a P-type distributed Bragg reflector (32), an ohmic contact layer (6), a graphite film current extension layer (7), and an upper electrode (11), which are arranged in bottom to the top order. USE - High power surface emitting laser with graphene film current extension layer. ADVANTAGE - The graphene thin film is used in the current extension layer, thus increasing light extracting efficiency, and thermal conductivity of surface emitting laser. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a High power surface emitting laser with graphene film current extension layer.
