    摘要： A Q-switched solid-state laser having a peak power of more than 1 MW comprises a resonator, which has a first and a second end mirror (6, 7) and optical elements which interact with the laser beam between the first and the second end mirrors (6, 7) and which comprise a pumped laser medium (1), wherein the laser beam is reflected from the first end mirror (6) in a direction which is at least substantially parallel to and equidirectional with the direction in which the laser beam is reflected from the second end mirror (7). The optical elements which interact with the laser beam between the first and the second end mirrors (6, 7) are designed in such a way that, upon propagation of an image (F) proceeding from the first end mirror (6), they have the effect that the image (F), after propagation via the optical elements lying between the first and the second end mirrors (6, 7) and reflection at the second end mirror (7), as viewed in the direction of propagation, is rotated about the beam axis (5) at least substantially by 180° with respect to its original orientation - as viewed in the direction of propagation - relative to the beam axis (5) and is laterally correct, wherein this rotated and laterally correct transfer of the image (F) takes place only on account of reflections of the laser beam at the optical elements lying between the first and the second end mirrors (6, 7) and at the second end mirror (7). The first and the second end mirrors (6, 7) are rigidly connected to one other.

    摘要： The present invention describes a self mode locking laser and a method for self mode locking a laser. The laser (1) comprises a resonator terminated by first (3) and second (4) mirrors and folded by a third mirror (5). The third mirror comprises a single distributed Bragg reflector (17) upon which is mounted a multilayer semiconductor gain medium (18) and which includes at least one quantum well layer and an optical Kerr lensing layer (22). Self mode locking may be achieved by configuring the laser resonator such that the lensing effect of the Kerr lensing layer acts to reduce an astigmatism deliberately introduced to the cavity mode. The self mode locking of the laser may be further enhanced by selecting the length of the resonator such that a round trip time of a cavity mode is matched with an upper-state lifetime of one or more semiconductor carriers located within the gain medium.

    摘要： Exemplary embodiments of apparatus, source arrangement and method for, e.g., providing high-speed wavelength tuning can be provided. According to one exemplary embodiment, at least one arrangement can be provided which is configured to emit an electromagnetic radiation that (i) has a spectrum whose mean frequency changes at an absolute rate that is greater than about 6000 (or 2000) terahertz per millisecond, (ii) whose mean frequency changes over a range that is greater than about 10 terahertz, and/or (iii) has an instantaneous line width that is less than about 15 gigahertz. According to another exemplary embodiment, at least one arrangement can be provided configured to, periodically and as a function of time, select at least one first electro-magnetic radiation based on a mean frequency of the at least one first electro-magnetic radiation, with the periodic selection being performed at a first characteristic period. The mean frequency can vary linearly over time, wherein the apparatus can emit at least one second electromagnetic radiation that has a spectrum whose mean frequency changes periodically as a function of time with a second characteristic period. Further, the first characteristic period can be greater than the second characteristic period.

    摘要： In einer Laseranordnung mit mindestens einem Lasermedium (2') zur Erzeugung einer Laseremission, einem Laserresonator mit einem Strahlgang (SG) mit einer Länge von wenigstens 20 cm und mit wenigstens einem Endspiegel (6') ist der Strahlgang (SG) innerhalb des Laserresonators zumindest teilweise als Freistrahloptik ausgebildet. Ein im Strahlgang angeordnetes Resonatorelement (9) weist wenigstens zwei optischen Flächen als mit der über den Strahlgang (SG) geführten Strahlung wechselwirkenden Flächen auf, wobei diese optischen Flächen so miteinander starr verbunden und gemeinsam im Strahlgang (SG) justierbar sind, dass sie bei Verkippung um einen Fehlwinkel im wesentlichen den gleichen Effekt auf die Führung des Strahlgangs (SG) erzielen, jedoch mit umgekehrtem Vorzeichen, so dass eine gegenseitige Kompensation von Verkippungsfehlern erfolgt.
