Ethernal™ SlowLight™ Single Frequency Fiber Laser Module
The Ethernal™ SlowLight™ lasers from Orbits Lightwave represent the state of the art in laser oscillators. The breakthrough “virtual ring” laser technology enables traveling wave oscillation in a compact, linear cavity. The traveling wave oscillation results in a pure high power (>350mw), record high signal to noise (>80dB) and side-mode suppression (>75dB).
The SlowLight™ technology slows the light group velocity, leading to ultra-low AM and FM noises and a record ultra-narrow instantaneous <1Hz Lorentzian linewidth and <200Hz 1/f linewidth over 1ms!.
Remarkably this performance is available in a compact, reliable and robust field-ready package. The StableLase™ technology greatly reduces the susceptibility to shock and vibration. In addition, passive temperature compensation in conjunction with the SlowLight™ technology offers the highest frequency stability in the industry.
This enables the Ethernal™ SlowLight™ fiber laser to operate at unprecedented levels of stability, reliability and low noise performance for even the most demanding research, industrial or military applications.
