WebWe use a black box, a laser, and a camera, the laser beam is expanded vertically to form a thin sheet of light, which we shine through slits on the left and right of the box. It's … WebLaser beams in the visible and NIR (λ = 0.3–3.0 μm) are transmitted by silica-glass fibers and have been used for transmitting the radiation of Ar, dye, Nd:YAG, and GaAs lasers. Excimer laser radiation at λ = 250–300 nm can be transmitted only through pure silica fibers, which are not very useful at shorter wavelengths.
