Abstract: The invention relates to an adjustment method, especially for adjusting optical or fibre optical components. Said method involves locally heating, in a defined manner, at least one first partial region of an adjustment region (106, 114) of an actuator (100, 200, 400), in such a way that compressive strains appear in at least one second partial region of the adjustment region of the actuator (100, 200, 400) as a result of the fact that said second partial region prevents the thermal expansion of the heated partial area. When the yielding point ?F of the material of the partial region is achieved, said compressive strains lead to a plastic deformation of the heated partial region. The heated first partial region shrinks during the cooling process, triggering a defined geometry modification of the actuator (100, 200, 400) following the cooling process.

Abstract: A package for maintaining alignment of components includes a frame and a beam with the beam attached to the frame and one end of the beam. One or more components are mounted to the beam. The frame and a portion of the beam are separated from each other by a channel which allows portions of the beam to flex substantially independently of the frame when a force is applied to the frame. Thus, the effects resulting from forces applied to the frame are not experienced by the beam, or are at least attenuated, so that the alignment of the components mounted on the beam is substantially preserved.

Abstract: The principles of the present invention relate to aligning optical components with three degrees of translational freedom. A lens pin, a lens base, and a molded package are aligned in a first direction, a second direction, and a third direction such that the signal strength of optical signals transferred between a lens included in the lens pin and the molded package is optimized. The lens pin is mechanically coupled to the lens base to fix the position of the lens relative to the molded package in the first direction. Subsequently, the lens base and the molded package are realigned in the second and third directions such that the signal strength is again optimized. The lens base is mechanically coupled to the molded package to fix the position of the lens base relative to the molded package in the second and third directions.

Abstract: A two piece nose assembly for optoelectronic devices is disclosed. The assembly includes a first piece having a central bore and an annular alignment recess about the central bore. The first piece can be attached to a housing of the optical device. The assembly also includes an annular second piece designed to receive an optical connector and having an outside surface designed to interference fit with an inside surface of the annular alignment recess. The annular second piece has an inside surface having a hardness of at least 35 on the Rockwell “C” scale. The first piece has an annular groove on an outside surface thereof that defines a lip adjacent to the housing. The annular groove has a tapered edge that facilitates an optimized angle of incidence for a laser beam used to weld the first piece to the housing.

Abstract: A laser system generates read, green and blue beams from a single laser beam generated by an IR continuous-wave laser using rare-earth or transition elements. Semiconductor diodes are used to excite IR continuous-wave laser and simple passive non-linear frequency conversion is used to generate the red, green and blue effective beams.

Abstract: The present invention provides a laser diode-pumped solid-state laser resonator which can be scaled and pumped longitudinally including in a folded or zig-zag resonator cavity. The resonator employs opposed laser rod crystals paired with pump light diodes in a configuration which ensures good spatial overlap and can permit the simultaneous generation of one or more laser wavelengths. The resonator also has at one end thereof a total reflector, eg. a laser rod crystal or a mirror and at the other end thereof, a partial reflector i.e. a mirror, to resonate and amplify the laser beam in the system and outcouple a portion thereof as desired.

Abstract: The invention relates to a method for producing a microsystem and from it forming a microsystem laser, which preferably has a vertical structural element by contacting of wafer plates, which carry different functional elements of a system, so that this system on the one hand thus includes heterogeneous functions such as actuators, optics, sensors, cooling systems, micromechanics and electronics, and on the other hand, the wafer carrying these functions permits a relatively homogeneous processing of quite similar functions integrated each on one wafer, so that the complexity of the system is created for the first time for the vertical arrangement of these functions.

Abstract: The invention provides a laser system with one or several micro-mechnically produced, actively controlled laser mirrors which are provided with an actuation device, so that the rapid manipulation of small laser mirrors is assured. The mirrors are designed so that they permit an economical production in large numbers.
