The nanosecond laser used in distributed Raman temperature sensing DTS features a minimum pulse width of 5 ns and peak power up to 30 W. It operates in both ACC and APC modes with stable signal output. The built-in pulse trigger output signal can synchronize with DTS acquisition cards.

GY-UNL-Chirp Sweep Pulse Light Source Module integrates a narrow-linewidth laser and modulator to generate chirped pulse light, making it suitable for chirped DAS systems.

This device features dual-output design for pulse signal light and intrinsic reference light, offering ultra-narrow linewidth, high pulse peak power, high switching extinction ratio, wavelength stability, low noise, low power consumption, and high reliability, making it a superior semiconductor laser product.
