[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0021] figure 1 The optical path diagram of the laser power detector according to the present invention is shown. As shown in the figure, the laser beam 2 is emitted from the laser exit surface 1 and first reaches the total reflection mirror 3. The total reflection mirror 3 is coated with a reflective film 9 on its incident surface, which is selected to enable the main part of the laser beam 2 to be reflected and only a small part to be transmitted. Among them, the reflected light beam 4 is output to the laser device for normal operation, and the transmitted light beam 5 is used to provide the photodetection element 8 for power monitoring.
[0022] In one embodiment, the refl...
