It essentially measures how well a laser beam can be focused, which directly impacts its performance in various applications such as material processing, medical procedures, and scientific research. Defining […]
Source: Optica Publishing Group The Poor Man’s Isolator in Photonics Introduction In photonics, optical isolators are essential for eliminating back reflections that can disrupt laser sources. While Faraday isolators are commonly used for this purpose, a cost-effective alternative known as the “Poor Man’s Isolator” can sometimes suffice. Working Principle The Poor Man’s Isolator involves passing
