摘要： PROBLEM TO BE SOLVED: To provide a surface emitting coupled cavity semiconductor laser device capable of producing one or more desired spatial modes at higher power levels and with greater device efficiency than those which would be feasible with known prior art VCSELs and VECSELs. SOLUTION: An active gain region sandwiched between a 100% reflective bottom Bragg mirror and an intermediate partially reflecting Bragg mirror is formed on the bottom surface of a substrate, to thereby provide a first (active) resonator cavity of a high power coupled cavity surface emitting laser device. The reflectivity of the intermediate mirror is kept low enough so that laser oscillation within the active gain region will not occur. The substrate is entirely outside the first active resonant cavity, but is contained within a second (passive) resonator cavity defined by the intermediate mirror and a partially reflecting mirror, where the second (passive) resonator cavity is subjected to only a fraction of the light intensity that is circulating in the gain region.

摘要： PROBLEM TO BE SOLVED: To improve a cleaning function, and effectively and efficiently improve cleaning operation compared with conventional arts. SOLUTION: In an apparatus and a method for generating high power laser radiation, the geometry of a resonant laser cavity defines a fundamental spatial or transverse cavity mode. A gain medium is disposed in the resonant cavity and an energy source energizes the gain medium within a first volume. This causes spontaneous and stimulated energy radiation propagated in the gain medium in a direction transverse to the fundamental cavity mode. Then the transverse radiation optically pumps a second volume of the gain medium around the first volume. When the intensity of emission is sufficiently high, inverse transformation and a gain are generated in the second volume. COPYRIGHT: (C)2007,JPO&INPIT

摘要： An active gain region sandwiched between a 100 % reflective bottom Bragg mirror and an intermediate partially reflecting Bragg mirror is formed on a lower surface of a supporting substrate, to thereby provide the first ("active") resonator cavity of a high power coupled cavity surface emitting laser device. The reflectivity of the intermediate mirror is kept low enough so that laser oscillatin within the active gain region will not occur. The substrate is entirely outside the first active resonator cavity to a level sufficient to cause lasing. The substrate is entirely outside the active cavity but is contained within a second ("passive") resonator cavity defined by the intermediate mirror and a partially reflecting output mirror, where it is subjected to only a fraction of the light intensity that is circulating in the gain region.

摘要： A wavelength selectable, controlled chirp, semiconductor laser system is provided. By coupling a passive cavity (11b), including an external output mirror (28) with a selected reflectivity, to the active cavity (11a) of a laser device, chirp is reduced by approximately the ratio of the length (1) of the active cavity to the length of the passive cavity (L). In such a device, changing the length of the passive cavity by manipulating the position of the output mirror allows for selecting an output wavelength of the laser device.
