Are newer diode lasers are more safe than gas based?
A. Diode lasers use less electricity and do not use water, so they are inherently easier to set up and maintain. However, lasers, including diode lasers, can be very powerful and extremely harmful if shown in someone’s eyes. Never point a stationary laser beam of any kind into someone’s eyes. This being said, lasers used as graphics and designs are not as dangerous because the beam is constantly moving, therefore the potential for eye damage is reduced to safe levels. When laser beams are used to shine down into an audience, this is called audience scanning.
