Abstract

PURPOSE:To perform laser processing steadily by finding out deterioration of mirrors and lenses at an early stage by providing the mirrors and lenses by which laser lights are transmitted or reflected with temperature detectors. CONSTITUTION:Laser oscillation is performed between mirrors 11 and 12 of a laser device and a direction of laser lights 13 is changed by a mirror 14 and the laser lights 13 are converged by a lens 15. The converged laser lights are used for laser processing. Each of the mirrors 11, 12 and 14 and the lens 15 is provided with a temperature detector 16. The temperatures of the mirrors 11, 12 and 14 and the lens 15 are detected when the laser device operates, thereby finding out an increase in temperature due to an enhancement of a heat absorption capacity caused by aging or contamination of the laser device at an early stage to make the laser processing stable.

In the case of , the laser output for laser oscillation decreases, and in the case of the mirror 3 and lens 4, absorption by the mirror 3 and lens 4 increases, and the ratio of the extracted laser output to the incident laser output decreases. .

その結果として、加工等が、安定して行なえず、またメ

実施例 以下、本発明の実施例について、第１図を参照して説明
する。EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG.

第１図において、１１．１２は、その間でレーザ発振し
、レーザ光１３を出力するミラーである。In FIG. 1, reference numerals 11 and 12 are mirrors that oscillate a laser between them and output a laser beam 13.

１５に取り付けである。14 is a mirror that changes the direction of the laser beam 13; 15 is a lens that focuses the laser beam 13; the laser beam that is focused by this lens 15 is used for processing or the like. A temperature detector 16 is attached to the mirrors 11, 12, and 14 and the lens 15.

戻すことができる。In the above configuration, when the mirrors 11, 12, 14 and the lens 15 are normal, the absorption rate on their surfaces is low;
The amount of heat generated is small. However, as the absorption rate increases over time or due to dirt, heat generation increases, and as a result, the absorption rate further increases and the temperature rises. Therefore, mirror 11
．． 12, 14 and the lens 16 at normal temperatures,
The temperature increases during abnormal times. For this reason, mirror 11.1
2. Check the temperature of the temperature detector 16 of the lens 14 and the lens 15 during normal operation, and check the temperature of the temperature detector 1 during abnormal operation.
By detecting the temperature of No. 6 and comparing it with the normal temperature, it is possible to early discover which mirror or lens is abnormal, and thereby the mirror or lens can be returned to normal condition by cleaning or the like.

なお、温度検出器１６をミラー１１．１２゜１４または
