1535nm5KHz-8ns-10 mJ-25mm high frequency laser

Operating Wavelength: typical:1550 nm Peak output optical power: typical:30 W Pulse Width: min:5 ns; typical:10 ns

The DTS pulsed laser integrates a nanosecond seed laser and fiber power amplifier for distributed fiber temperature sensing, laser ranging, and fiber sensing. Optimized nanosecond drive circuitry and a low-noise erbium-doped amplifier produce stable pulses with high peak power and low distortion. External triggering and serial configuration of width, peak power, and other parameters provide high integration, compact size, and easy setup. Rigorous environmental testing supports long-term reliability and stability.

Operating Wavelength Range: typical:1550.12 nm Output Optical Power: typical:10 dBm Equivalent spectral linewidth: typical:3 kHz

The UNL fiber-laser series for sensing offers narrow linewidth, long coherence length, low noise, and strong environmental-interference resistance. Distinctive optics and precise drive/control eliminate external temperature and vibration effects on wavelength for stable single-longitudinal-mode, ultra-narrow-linewidth, single-frequency output. Serial configuration, high integration, compact size, and easy setup are provided, with custom single-mode or PM-fiber outputs.
