| 英文摘要 | PCT No. PCT/SE97/00562 Sec. 371 Date Oct. 1, 1998 Sec. 102(e) Date Oct. 1, 1998 PCT Filed Apr. 1, 1997 PCT Pub. No. WO97/37265 PCT Pub. Date Oct. 9, 1997Arrangement for generating well-defined beam distribution over a surface or in a volume by means of a diffraction optical element (17). The arrangement includes at least one laser source (14), an optical filter means, preferably a mode-selective filter (16), a diffraction optical component (17) as well as possible coupling and focusing elements (15, 18). Said components, means and elements are positioned and fixed in a common unit and that the filter (16) is so developed that the beam from the source (14) after passage through said mode-selective filter (16) occurs essentially in one mode. |
