Raman amplifier modules can be used in distributed fiber optic vibration systems, capable of increasing fiber optic sensing distances up to 40km or more.
This PM fiber acousto-optic demodulator (1064 nm, 200 MHz) is primarily used for seed source selection and frequency downshifting in ultrafast laser systems.
APD12702 Series: Temperature compensation, UV-enhanced sensitivity, 3mm photosensitive area. Ideal for low-light signals, fluorescence measurement, and chemical analysis.
Introduces the configuration of the pulsed laser for DTS temperature sensing, including how to set the ACC and APC modes, the trigger method and the pulse width parameters.
