Wavelength-Tunable Polarization-Maintaining Laser Source NLPM-T50
NLPM-T50 is a wavelength-tunable, narrow-linewidth PM laser based on external-cavity technology. Tunable wavelength, narrow linewidth, long coherence length, low noise and environmental interference resistance provide high value for photoelectric sensing and inspection. Precision drive/control enables stable single-longitudinal-mode, narrow-linewidth single-frequency output. Host software tunes C-band ITU-T wavelengths and power.
