| 20100303105 | GENERATING PULSE TRAINS IN Q-SWITCHED LASERS - The invention relates to methods and systems for generating a pulse train having several individual pulses, wherein the individual pulses have a desired pulse characteristic, by means of a Q-switched solid state laser system, which includes, e.g., a modulator for influencing the pulse characteristic of the individual pulses. The methods include (a) generating individual pulses of a pulse train, each pulse having a pulse characteristic, by applying a temporal initial modulation signal; (b) detecting the pulse characteristic of the individual pulses of the generated pulse train; (c) generating a modified modulation signal in correlation to the detected and the desired pulse characteristic of the individual pulses of the pulse train, and applying the modified modulation signal to the modulator to generate a pulse train with a modified pulse characteristic; (d) repeating step (c) until the modified pulse characteristic fulfills a predetermined termination criterion and then using the modified modulation signal as an optimum modulation signal; and (e) generating a pulse train with the desired pulse characteristic of the individual pulses thereof by applying the optimum modulation signal. | 12-02-2010 |

| 20090028495 | ELECTRO-OPTICAL HYBRID CONNECTION ASSEMBLY - An electro-optical hybrid connection assembly provides an optical connection of at least a first optical fiber and a second optical fiber that define a fiber axis and an electrical connection of at least a first electrical conductor and a second electrical conductor. The assembly includes a first connector and a second connector. The first connector includes a first ferrule that encloses the first optical fiber, a centering sleeve surrounding the first ferrule and projecting beyond at least one end of the first ferrule, and at least one electrical plug-in contact connected to the first electrical conductor. The second connector includes a second ferrule enclosing the second optical fiber, and at least one electrical plug-in contact connected to the second electrical conductor. Each of the two optical fibers has a plane fiber end aligned at right angles to the fiber axis and provided with an anti-reflection coating. | 01-29-2009 |
