    • 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.

    • 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.
    • 夹在100%反射底部之间的主动增益区域。 布拉格反射镜和中间部分反射布拉格反射镜形成在支撑基板的下表面上,从而提供高功率耦合腔表面发射激光器件的第一(“有源”)谐振腔。 底部反射镜优选与外部散热器直接热接触,以获得最大的散热效果。 中间反射镜的反射率保持足够低,从而不会发生主动增益区域内的激光振荡。 衬底完全在第一有源谐振腔内,达到足以引起激光的水平。 衬底完全在有源腔体的外部,但是被包含在由中间反射镜和部分反射的输出反射镜所限定的第二(“无源”)谐振器腔中,其中它仅受到在 增益区域。 活性增益区优选地被电激励,其中由底部反射镜和散热器之间的氧化物电流孔形成的圆形底部电极,以及形成在衬底的上表面上的环形顶部电极。
