Mirror Laser Discharge 1.0 mm beam Partial mirror Electrodes Power supply Review A helium-neon laser (λ = e33 nm) is built with a glass tube of inside diameter 1。0 mm. as shown in (Figure 1). One mirror is partially transmitting to allow the laser beam out. An electrical discharge in the tube causes it to glow like a neon light. From an optical perspective, the laser beam is a light wave that diffracts out through a 1.0-mm-diameter circular The angle...
