Abstract
A right angle reflection prism includes first and second surfaces that form a right angle, and a third surface connected to the first and second surfaces. The right angle reflection prism causes a laser beam, which is made incident on the first surface and with which a material to be processed is irradiated, to be totally reflected by the third surface so as to be emitted from the second surface. A sensor detects a power of a laser beam that has passed through the third surface.

A laser power monitoring device, comprising:
- a right angle reflection prism including first and second surfaces that form a right angle, and a third surface connected to the first and second surfaces, a laser beam for irradiation of a material to be processed being incident on the first surface, and being totally reflected by the third surface so as to be emitted from the second surface;
- and
- a sensor configured to detect a power of a laser beam that has passed through the third surface.
