| 20110102882 | BLUE EXTENDED SUPER CONTINUUM LIGHT SOURCE - A new blue extended super continuum light source is claimed. When pulses of partly coherent monochromatic “pump” radiation of essentially constant amplitude is propagating through a microstructure fibre medium within a region of anomalous dispersion of the medium, then, provided the medium has a finite nonlinear coefficient of the index of refraction, the pump pulse is subject to a modulation instability. This instability results in the generation and exponential growth of sidebands, the two closest to the “pump” frequency being the dominant ones. The modulation frequency is proportional to the square root of the power in the carrier wave. In the time domain this leads to that the interaction between the medium and the radiation results in contraction of the width of the amplitude peaks, which results in formation of a train of narrow pulses with Tera Hertz repetition rate. | 05-05-2011 |
| 20110019701 | SYSTEM, DEVICE AND METHOD FOR EXTENDING THE LIFE-TIME OF AN OPTICAL SYSTEM - The invention relates to an optical system arranged to provide an output which, in operation, comprises at least one figure of merit, Q. The system comprises an optical component having multiple working areas, said component being mounted on a support member. The system further comprises an optical beam path arranged to bring light into interaction with at least one working area of the optical component wherein the position of said working area(s) may be selected by relative movement between said path and said component while keeping Q substantially unaffected by said movement. | 01-27-2011 |
| 20100329292 | SYSTEM, DEVICE AND METHOD FOR STABILIZING THE OPTICAL OUTPUT POWER OF AN OPTICAL SYSTEM - A light source system for delivery of light including a light source having an output arranged to emit light in an output path, the output path including an unguided section and an at least partially transmissive optical component wherein the optical component provides at least one residual reflection when the system is in use and a detector system is arranged to detect said residual reflection. The detector is in one embodiment arranged to produce at least one feedback response arranged to stabilize the optical output of the light source system. Hereby a feedback may be implemented with little or no reduction of performance. | 12-30-2010 |
| 20100296529 | MODE-LOCKED FIBER LASER WITH IMPROVED LIFE-TIME OF SATURABLE ABSORBER - A mode locked fiber laser system is arranged to have a lasing bandwidth and having a linear cavity, the cavity including a gain medium, a saturable absorber having a saturation power, and a filter having a spectral response, wherein the mode locked fiber laser system is arranged so that substantial CW mode locked operation is obtainable with less than 3 times the saturation fluence impinging on the saturable absorber. | 11-25-2010 |
