What is the difference between Diode & Helium-Neon lasers?
Essentially, both types of lasers do the same thing – provide a bright, crisp line that is highly directional and controllable. It’s the way the light is produced that differs. Briefly, the Helium-Neon laser is a gas-filled tube that generates the red light. The Diode laser utilizes solid state technology and generates the red light from a wafer.
