Some units use crows to fly laser Pointers to mark aircraft targets at night. This is done to ensure that "friendly" and "enemy" targets do not go wrong. Friendly targets may wear infrared radiation devices for night vision only (e.g., pilots). To pinpoint the enemy fighter's position, you simply illuminate the target with a green laser beam that the attack aircraft can detect. This is one of the most accurate types of target marking. Lasers and mirrors work together. Lasers are created when light bounces back and forth between a series of mirrors. Laser Pointers use the same method but are compressed to a compact handheld size.
In addition to the mirror, the red Laser Pointer has two other important components. The focused light from the mirror is a laser, but where does the light come from? Use batteries to generate energy, and use laser diodes to convert the energy into light. As semiconductor diode lasers have improved in power and efficiency, inexpensive battery-powered lasers in the form of laser Pointers have emerged, but their optical power is still far beyond the limit (laser class 2 or 2M). It is considered harmless to humans. Short eye contact. These beam sources are also sold as laser Pointers, but they are very risky to use, cause a lot of injury to people, and can be sued for damage caused.
