By an external resonator controlled semiconductor laser

摘要

one end of a halbleiterlasers (1) with a antireflexionsfilm (1a) coated. an external resonator is a beugungsgitter (2) and an external reflective mirror (4) is formed. in addition, an strahlteiler (3) between the beugungsgitter (2) and the external reflective mirror (4) are provided.ausgangslicht of the antireflexionsfilm (1a) of the halbleiterlasers (1) through a konvexlinse (5a) in parallel light converted and the strahlteiler (3) form. the parallel light (13a) changes its lichtweg the strahlteiler (3) and is then fed into the external resonator.the wavelength of the parallel light (13a) is the beugungsgitter (2), so that the light of a selected wavelength, and a phase in the external phasenzustand in transport.a part of the resonant light is reflected by the strahlteiler (3) and a reflected light on the halbleiterlaser (1) on the konvexlinse (5a) zuru00fcckgekoppelt. if the light zuru00fcckgekoppelt is the halbleiterlaser (1) light with close spectral line width.the light from the other end, which is not a antireflexionsfilm (1a) is coated, the halbleiterlasers (1) spent, and by a konvexlinse (5b) into parallel light converted. this parallel light (13b) is a lichtisolator (6) is fed and then through a konvexlinse (7) in a phaseroptik (8). that the...
