用于通过纤维耦合优化的射束参数乘积产生二极管激光辐射的二极管激光器结构
Abstract:
本发明涉及一种二极管激光器结构(2)，具有多个彼此相邻地设置的带状发射器(31至38)，这些带状发射器以其SA轴线在相同的方向上取向并且在该方向上彼此相对错位地设置，其中，这些带状发射器(31至38)中的至少几个的分别涉及SA轴线的射束参数乘积(BPPSA)不同，根据本发明提出，这些带状发射器(31至38)的分别涉及SA轴线的射束参数乘积(BPPSA)从该二极管激光器结构(2)的中部起朝该二极管激光器结构(2)的两个边缘尤其是关于该二极管激光器结构(2)的中部镜像对称地减小。
Abstract(English):

In a diode laser structure (2) with a plurality of strip emitters (31 to 38) arranged side by side whose SA-axes are arranged in the same direction and at an offset to each other in this direction, wherein the beam parameter products (BPPSA) of at least a few of the strip emitters (31 to 38) are each shifted relative to the SA-axis, according to the invention the beam parameter product (BPPSA) ofthe strip emitters (31 to 38) decreases, starting from the middle of the diode laser structure (2), to the two edges of the diode laser structure (2), in particular in a mirror-symmetrical manner and/or from the middle of the diode laser structure (2).
