A single-mode laser is a laser that emits light in a single, well-defined mode or pattern. This mode can either be a single spatial mode, meaning the light is emitted in a single, narrow beam with a well-defined transverse intensity profile, or a single longitudinal mode, meaning the light is emitted at a single, well-defined frequency with minimal spectral spreading. Due to their high spectral purity and stability, single-mode lasers are used in various applications, such as telecommunications, spectroscopy, and precision metrology.
