Source: Scikit-learn Understanding Clustering in Laser Physics Understanding Clustering in Laser Physics What is Clustering? Clustering in laser physics refers to the tendency of laser-active ions in a solid-state doped insulator laser gain medium to form clusters rather than being randomly spread. This clustering effect can lead to energy transfers between laser ions, which can
Source: ResearchGate Lasing Without Inversion Lasing Without Inversion Understanding the Concept Traditionally, lasers operate on the principle of population inversion, where the upper laser level has a higher population than the lower level, enabling stimulated emission and positive net gain. However, in the 1990s, researchers discovered that lasing without inversion is feasible by inducing quantum
