How does beam divergence affect laser performance?

• A. It enhances the focusability of the beam
• B. It influences precision over distances
• C. It has no effect on performance
• D. It increases the diameter of the beam

Answer: (B)

Beam divergence is a critical factor in determining the performance of a laser. It refers to the gradual spreading of the laser beam as it travels away from the laser source. As the beam diverges, its diameter increases, which can affect how effectively the beam interacts with targets at varying distances. The influence of beam divergence on precision over distances is significant. A laser with low divergence will maintain a narrow beam profile over long distances, allowing for more precise targeting and effective energy delivery. In contrast, high divergence can lead to a wider beam that is less accurate when aiming at specific points or targets, particularly at greater ranges. This effect is crucial in applications such as laser cutting, optical communications, and medical procedures, where precision is paramount. While beam divergence can increase the diameter of the beam as it travels, the primary concern in this context revolves around how divergence impacts the accuracy and efficacy of the laser at a distance. Thus, its influence on precision makes it a vital aspect of laser performance.
