ASE Light Source

ASE light source is commonly used in high precision fiber optic gyroscope. Compared with the commonly used flat spectrum light source, ASE light source has better symmetry, so its spectral stability is less affected by the ambient temperature change and pump power fluctuation; meanwhile, its lower self-coherence and shorter coherence length can effectively reduce the phase error of fiber optic gyroscope, so it is more suitable for application in Therefore, it is more suitable for high precision fiber optic gyro.
