The term 'HIGH-TECH POINTER' can be broken down into two crossword solutions: 'LASER' (5 letters) and 'REDLASER' (8 letters). A LASER is a device that emits a beam of light that is highly concentrated and coherent, meaning that all the waves of light are in phase with each other. Red lasers are lasers that emit light in the red spectrum, which is the longest wavelength of visible light. High-tech pointers are devices that use lasers to point at objects or surfaces, such as a presentation slide or a whiteboard.
