大功率CO_2激光器的功率测量关键在于大功率激光光束取样杆应在不影响光束工作条件下取样测量激光光束功率,被测量的激光功率可高达上万瓦.在研制反射式取样功率计过程中,重点考虑在保证测量精度及稳定性条件下,尽量使仪器成本降低.反射式的光学系统可以减少加工费用;反射口径可做得比较大,适用于大口径激光束测量,同时反射镜重量轻.另一方面,采用自行设计与研制的温差多接点热电堆探测器,不仅成本低而且 High-power CO_2 laser power measurement key lies in the high-power laser beam sampling rod should not affect the working conditions of the beam sampling laser beam power measurement, the measured laser power up to 10,000 watts.In the development of reflective sampling power meter process, Focus on ensuring the measurement accuracy and stability conditions, as far as possible to reduce the cost of the instrument. Reflective optical system can reduce processing costs; Reflective aperture can be done relatively large, suitable for large diameter laser beam measurement, while the reflector light weight. On the other hand, the thermocouple multi-junction thermopile detector designed and developed by itself is not only low in cost but also
