We hate to admit it, but laser cutter beam alignment is no easy task. To greatly assist in this endeavor, though, some folks tend to mix a red diode laser into the path of the beam. Others ...

Alignment interfaces and mechanisms vary and can have different implementations. Some mechanisms are built into the device permanently. Others are part of a fixture that is temporarily attached, such ...

Nevertheless, if the wideband split effect is properly utilized, it can also bring benefits via sensing split directions for channel training. Hence, this paper proposes a novel wideband beam ...
