20090122824 | SEMICONDUCTOR LASER APPARATUS - A semiconductor laser apparatus having a first clad layer, a first guide layer, an active layer, a second guide layer, and a second clad later formed in the order listed is disclosed. A layer serving as an optical waveguide is formed between the first clad layer and the second clad layer and wherein the layer serving as an optical waveguide is formed with such a thickness that not only light of a fundamental mode but also light of a higher-order mode is guided. An absorption layer absorbing the light of a higher-order mode is formed in a position to suppress only the oscillation of the light of a higher-order mode, the absorption layer being formed as a layer forming part of the layer to serve as an optical waveguide. | 2009-05-14 |
20090122825 | Laser system - A method/apparatus may comprise a seed laser oscillator producing an output which may comprise: a first gas discharge excimer or molecular fluorine laser chamber; a line narrowing module within a first oscillator cavity; a laser amplification stage receiving the output of the seed laser oscillator which may comprise: a ring power amplification stage; a coherence busting mechanism intermediate the seed laser oscillator and the ring power amplification stage which may comprise a beam splitter separating the seed laser output into a main beam and a beam entering an optical delay path which may have a delay length longer than the coherence length of a pulse in the seed laser output and may have a beam angular offset mechanism offsetting a delayed beam and the main beam. | 2009-05-14 |
