| 摘要 |
The invention relates to an apparatus ( 1 ) for generating and transmitting laser light beams ( 14 ), comprising a semiconductor layer structure ( 2 ), two light conducting fiber elements ( 10, 16 ) coupled at two sides of the semiconductor layer structure ( 2 ) to an active layer ( 3 ) comprised by the semiconductor layer structure ( 2 ) and made of a semiconductor material which is electrically excitable to generate light, and a laser resonator ( 7 ) with optical feedback means between which the active layer ( 3 ) is positioned, the laser resonator ( 7 ) including an optical grating to select laser light beams ( 14 ) of at least one predetermined laser wavelength. The optical grating is formed as a fiber grating ( 6 ) outside of the active layer ( 3 ) in a portion of one of the two light conducting fiber elements ( 10 ) comprised by the laser resonator ( 7 ).
