What Do Scientists Love About Frequency-Stabilized Lasers For Fiber Optic Sensing?
Having a frequency-stabilized laser as part of the measurement system reduces the amount of noise present in the measurement system, making it more reliable when used globally in industrial, research, and monitoring measurements. Frequency-stabilized lasers produce a steady output frequency, and because of this, they are excellent at measuring very small variations in the output of a fiber-optic system. 1) Reduction of signal noise In addition to providing a stable output frequency, a frequency-stabilized laser holds the frequency of the laser stable, thus reducing signal fluctuations and introducing less noise into the system. With less interference from other signals, frequency-stabilized lasers produce a cleaner signal from the sensor, making it easier to analyze data collected from a fiber-optic-based sensor and recognize very small changes in measurement conditions. 2) Improved long-distance performan...
