Frequency-Stabilized Laser for High-Sensitivity Sensing
This frequency-stabilized laser for highly sensitive sensing is designed for precision measurement, optical sensing and high-resolution spectroscopy. Narrow-linewidth single-frequency laser technology and precision frequency stabilization provide extremely low frequency drift and highly coherent output. Excellent power and wavelength/frequency stability improve sensing-system SNR and detection resolution, especially for weak-signal detection and long-duration data acquisition.
