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!.
