Abstract
Laser warning systems are provided for providing an alert when exposure to laser light sources is detected. The system includes a colloidal quantum dot detector module including a colloidal quantum dot photodetector and a processor coupled to the colloidal quantum dot detector module. The system detects interference patterns generated in the colloidal quantum dot detector module by light illuminating the laser warning system and determines if the light illuminating the laser warning systems is laser light based on a magnitude of interference infringes generated by the light illuminating the laser warning system.
