Description:
A laser diode is electrically a PIN diode. The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively. Unlike a regular diode, the goal of a laser diode is to recombine all carriers in the I region, and produce light. The laser head is composed of a light-emitting tube, condenser lens, and adjustable copper sleeve and it is assembled when delivered, the focal length of the lens is adjusted glued by a strong glue stick, which can work directly after connecting to a 5V DC power supply. Pay attention to the laser cell to prevent it from being burnt or from battery explosion due to a short circuit when removing the battery. The principle of laser emission and the specificity of the generation process determines the characteristics of laser which common light does not have: nice monochromaticity, coherence and directionality, and high brightness.

Application:
- Electronic pointer: the teacher can use a laser pointer to indicate during teaching.
- Electronic level meter: the motor drives the head for rotation, and a straight line is projected on the wall for horizontal reference during decorating or posting pictures.
- Micro LCD projector: Remove the condenser so that the laser can produce a clear projection on the wall through the controllable LCD screen.
- Remote laser monitor: point the laser on the glass of the room to be monitored, receive the laser beam reflected back by the glass, and then detect the vibration of the glass to figure out sound in the room.
- Remote light-control anti-theft alarm: install laser diode and photosensitive resistance on one edge of the fish pond or watermelon patch to be protected and reflectors on the other three edges to form a protective zone.
- Remote laser wireless communication: place a pair of laser transceivers on two distant roofs facing each other respectively, you can send and receive files and even connect to the network with the use of the serial communication protocol of the microcontroller.
