    They are intended not to cause long-term damage to eyes. The emitters are usually lasers, making what is termed a laser dazzler. Most of the contemporary systems can be carried by a person, and operate in either the red (a laser diode) or green (a diode-pumped solid-state laser, DPSS) areas of the electromagnetic spectrum. The green laser is ...
