Product Description
The Clear Align Razor Laser™ is an all-fiber distributed feedback (DFB) laser and amplifier available on ITU-grid wavelengths in the C-band with temperature tuning. The compact, rugged package provides outstanding passive vibration and acoustic damping resulting in an extremely low sensitivity to environmental noise.
With output powers in excess of 25 mW, the Razor Laser™ provides exceptionally low phase noise and narrow linewidth (<1 kHz) suitable for a wide range of sensor, spectroscopic and interferometric applications. Free of mode-hops and burst noise, the Razor Laser™ exhibits exceptionally stable output power. Optional features include RIN suppression, polarization maintaining fiber, and digital controls.
