PDH Sensing Demodulator
This PDH frequency stabilization system features a typical laser linewidth of 0.1 kHz, a tunable range of 1549.4–1550.3 nm, and supports 1–12 strain sensing channels. With a feedback speed of up to 5 kHz (customizable), it is suitable for scenarios requiring precise laser frequency control, such as optical communications and precision sensing applications.
