WebCompare with where wo and θo are the beam waist and divergence prior to the lens (of focal length f), d is the distance from w o to the lens, and z is the distance from the lens. The distance d 1 + d 2 should be 750mm. After a 10X expansion, the divergence angle is then equal to (1/10)* 1.41 mrad, or 0.141 mrad. Web22 dec. 2024 · How Laser Beams are Made. Many types of devices emit lasers, such as optical cavities. These are chambers that reflect the light from a material that emits electromagnetic radiation back to itself. They're generally made of two mirrors, one at each end of the material such that, when they reflect light, the beams of light become stronger.
