Usually, there is a laser diode that is optically coupled to the fiber.

Yes, an optical reader that uses laser beams to read bar codes is commonly known as a laser barcode scanner. These devices emit laser light to scan and capture the information encoded in bar codes, which is then processed and converted into readable data. Laser scanners are widely used in retail, logistics, and inventory management due to their speed and accuracy. They can read bar codes from a distance and are often preferred for their efficiency in high-volume scanning environments.
CD's and DVD's are not magnetic. They are optical storage devices that are read with LASER beams.
Laser beams are typically coherent, monochromatic, and highly directional. They can propagate over long distances without significant divergence, allowing for precise focusing of the beam. Laser beams also have high intensity and can be easily manipulated using optical components.
Sapphire is used as a "window" for laser beams and in focusing light in fiber optics.
Some examples are Light bulb, fiber optics, laser surgury intruments.
Yes, laser beams can carry signals just like radio waves, but they are typically used in optical communication systems. Laser beams have a higher frequency and bandwidth compared to radio waves, making them suitable for high-speed data transmission over shorter distances through optical fibers.
The laser shines through the fiber optic cable because the edge of the inside of the cable can act as a mirror. This is called internal reflection.

Your answer is correct.
A dual laser beam refers to a setup where two laser beams are emitted simultaneously. This can be used for various applications such as precision cutting, 3D printing, or optical trapping in scientific research. By having two beams, it can allow for more complex operations or increased efficiency in certain processes.
