Definition/Scope: (JP 3-09.1) Laser designators may emit a narrow, collimated beam of laser pulses. The laser designator possesses several unique characteristics, including beam divergence, which significantly impact laser operations. Another characteristic is the single color (wavelength) of the laser pulses. Laser wavelengths span from the ultraviolet to the visible to the far IR spectrum. Wavelength determines whether the sensor is visible to the human eye or specific sensor. Current tactical laser designators fall in the near IR band and are invisible to the human eye. The beam is susceptible to enemy acquisition throughout the laser energy wavelength.
