Abstract: The invention pertains to a remote-controlled miniature aircraft with at least one lift surface (17), with at least one pair of propeller drives (12, 13) and with a weight element (20), the position of which can be varied in the longitudinal direction of the miniature aircraft (10) in order to change the center of gravity of the miniature aircraft (10). In order to realize a more compact and more robust construction with improved flying characteristics, the lift surface (17) of the miniature aircraft (10) is arranged above a plane defined by the rotational axes of the propeller drives (12, 13) in order to generate a lifting force for taking off and/or landing from a standstill.

Abstract: Laser machining system (60) comprises a high-power laser (61) for generating a high-power pump laser beam (HP-MM), control signal laser (62) for generating a control signal laser beam (SS), an optical fiber (64) leading from the two lasers to a laser machining head (63). The optical fiber has an SRS amplifier fiber (65) with an inner fiber core (65a) of higher brilliance and with an outer fiber core (65b) of lower brilliance surrounding the inner fiber core. The control signal laser beam (SS) is coupled into the inner fiber core and the pump laser beam (HP-MM) is coupled into the outer fiber core. The radiation component converted from the outer fiber core into the inner fiber core due to the SRS amplification is adjusted by means of the coupled-in power of the control signal laser beam (SS) to adjust the brilliance of the machining laser beam leaving the SRS amplifier fiber.

Abstract: A laser amplifying system is provided having a solid body arranged in a laser radiation field and including a laser active material that is pumped with a pumping light source. The solid body has a cooling surface and transfers heat created therein to a solid cooling element via the cooling surface. In this manner, a temperature gradient results in the solid body in a direction towards the cooling surface. The solid cooling element forms a carrier for the solid body. The laser radiation field propagates approximately parallel to the temperature gradient in the solid body. By enabling heat to be transferred to the solid cooling element via the cooling surface, this structure enables the solid body to be pumped at a high pumping power. Further, since the laser radiation field propagates approximately parallel to the temperature gradient in the solid body, the radiation field sees the same temperature gradient in all cross-sectional areas. Thus, the temperature gradient does not lead to an adverse effect on the beam quality of the laser radiation field at high pumping power.

Abstract: In a solid-state laser amplifier including at least two laser-active media in a common laser radiation field, the laser-active media do not form a hard aperture for the laser radiation field. Each of the laser-active media define a plane that is penetrated by the laser radiation field. The laser amplifier includes at least one focusing optical element disposed in the laser radiation field between two adjacent laser-active media. A focal length and a distance of the focusing optical element from the planes of the two adjacent laser-active media are selected such that the planes of the laser-active media are approximately mapped onto each other by a near-field far-field transformation.

Abstract: A beam shaping optical arrangement combines three incoming laser beams that are mutually laterally offset in two orthogonal directions (X and Y), including an incoming first central laser beam and second and third incoming beams laterally offset in the X direction on either side of the central beam, into one outgoing combined laser beam. The arrangement includes two lateral displacement optical units though which the laterally offset incoming beams are transmitted and that laterally displace the two laterally offset incoming beams along the X direction towards the incoming central beam but which do not laterally offset the incoming central beam. The lateral displacement units include a material having a higher refractive index than a medium located in an optical path of the central laser beam, and the optical path length traversed by the incoming laterally offset laser beams is selected such that, after transmission though the optical units, the diameters of the central laser beam and the laterally offset laser beams are approximately equal at least in the X direction, and a divergence of the central laser beam is approximately equal to a divergence of the laterally offset laser beams.
