Ethernal™ SlowLight™
 
Ultra-narrow 200 Hz Linewidth, Super-stable and Low-noise Fibre Lasers
 
The Ethernal SlowLight laser from Orbits Lightwave is an industry-leading ultra-stable, low-noise fibre laser. The breakthrough "virtual ring" laser oscillator enables travelling wave and slow light oscillation in a compact, linear, all fibre cavity.
 
Traveling wave oscillation results in higher power, lower noise and a higher sidemode suppression ratio.
 
The SlowLight technology also effectively increases the cavity lifetime resulting in ultra low FM and AM noise performance.
 

Features	Applications
Linewidth < 200 Hz or < 400 Hz Optical signal to noise > 80 dB Sidemode suppression ratio > 75 dB Industry's lowest amplitude & phase noise Compact all-fibre "virtual ring" architecture High power single oscillator > 350 mW StableLase™ reduces sensitivity to shock and vibration by five orders of magnitude	Acoustic sensing Marine and perimeter security LIDAR, ALSM or laser altimetry Injection seed lasers Coherent communications RF and microwave photonics Spectroscopy, gas absorption testing Pipeline monitoring, leak detection Defense, motion & intrusion detection Oil and gas exploration systems Metrology

The Ethernal SlowLight fibre laser represents a new benchmark in laser performance. The highly integrated and robust fibre laser utilizes passive stabilization and eliminates the necessity for wavelength and temperature control.

 
Orbits Lightwave Fibre Laser Modules are available as Low (LP) and High Power (HP) variants

StableLase technology greatly reduces the susceptibility to shock and vibration by more than five orders of magnitude. This enables the Ethernal SlowLight fibre laser to operate at unprecedented levels of stability and performance for demanding industrial or military applications.
