Visible Laser
A visible laser is a laser that emits a laser beam in the visible spectrum. The visible spectrum has wavelengths roughly between 380nm - 750nm and can be visually seen by the human eyes.
Below is a diagram of different types of visible lasers associated with its lasing medium and wavelength. Notice in the diagram below, the visible laser section is labeled "VISIBLE LASER".
