SLED (Superluminescent Diode) broadband light source is a special semiconductor light source with performance between laser diode and light emitting diode. A semiconductor light emitting device with wide spectrum, weak temporal coherence, high power, and high efficiency. Its spectral bandwidth is relatively narrow compared to ultra wideband light sources, typically in the spectral range of 6nm to 100nm.
Ultra wideband light sources use multiple SLED lasers and broadband coupling technology, which can achieve continuous spectral output exceeding 400nm and have high power spectral density, good stability, and reliability.
