Description

Изобретение относитс  к лазерной обработке материалов, в частности к оборудованию дл  ее выполнени .The invention relates to laser processing of materials, in particular to equipment for its implementation.

Целью изобретени   вл етс  повышение КПД при облучении обрабатываемой поверхности нормально направленным излучением.The aim of the invention is to increase the efficiency upon irradiation of the treated surface with normally directed radiation.

На чертеже представлена схема установки .The drawing shows the installation diagram.

Установка содержит лазер 1, пол ризатор 2 излучени , оптический элемент 3 дл  изменени  пол ризации излучени  и фокусирующий объектив 4, установленные последовательно вдоль оптической оси 5 установки, и отражающее зеркало 6. Вдоль осей 7 и В, расположенных под равными углами к оптической оси 5 установки, дополнительно установлены два фокусирующих объектива 9 и 10, два оптических элемента 11 и 12 дл  изменени  пол ризации излучени  и два отклон ющих зеркала 13 и 14. На оси 8 между дополнительными оптическим элементом11 дл  изменени  пол ризацииThe apparatus comprises a laser 1, a radiation polarizer 2, an optical element 3 for changing radiation polarization, and a focusing lens 4 mounted in series along the optical axis 5 of the apparatus and a reflecting mirror 6. Along axes 7 and B located at equal angles to the optical axis 5 installations, two focusing lenses 9 and 10, two optical elements 11 and 12 for changing the polarization of radiation and two deflecting mirrors 13 and 14 are additionally installed. On the axis 8 between the additional optical element 11 for changing the polarization

Установка работает следующим образом .Installation works as follows.

Включают лазер 1. Линейно-пол ризованное излучение лазера 1 проходит пол ю ризатор 2, оптический элемент 3, измен ющий пол ризацию проход щего через него излуче ни  с линейной на круговую. Это излучение фокусирующим объективом 4 направл етс  на обрабатываемый материал 17. Часть излучени , отражаема  материалом 17 в апертуру фокусирующего объектива 4, пройд  его, поступает на оптической элемент 3. измен ющий пол ризацию излучени  с кругоBOfi на линейную. Излучение, отраженное материалом 17 в апертуру фокусирующегоTurn on the laser 1. Linear-polarized radiation from laser 1 passes through the polarizer 2, the optical element 3, which changes the polarization of the radiation passing through it from linear to circular. This radiation by the focusing lens 4 is directed to the material being processed 17. A part of the radiation reflected by the material 17 into the aperture of the focusing lens 4, passing through it, is transmitted to the optical element 3. Changing the radiation polarization from circular BOfi to linear. Radiation reflected by material 17 into the focus aperture
