Ultra Narrow Linewidth Laser

This novel laser architecture enables traveling wave oscillation in a compact all fiber laser cavity.

Ultra narrow linewidth laser.

The traveling wave laser field eliminates spatial hole burning a feat. The laser and its control electronics are integrated into a single module that uses precision feedback monitoring to provide ultra low noise performance and superior wavelength stability. By combining an interferometric working principle with ultra low noise electronics a superb sensitivity is achieved. Overall solstis is the quietest and most stable tis laser available with free running linewidths close to 50 khz.

But even the manufacturers face a challenge on accurately measuring the linewidth of such lasers. Orbits lightwave offers ultra stable low noise high power fiber lasers in the 1060nm and 1550nm wavelength range. Our flagship ethernal lasers are based on orbits proprietary virtual ring laser cavity. A single wavelength 1544 nm hybrid extended distributed bragg reflector laser with 24 x00a0 mw output power and a lorentzian linewidth of 320.

Recently less than 1khz linewidth fiber lasers have been commercialized. The laser and its control electronics are integrated into a single module that uses precision feedback monitoring to provide ultra low noise performance and superior wavelength stability. We demonstrate ultra narrow linewidth fixed wavelength hybrid lasers composing a semiconductor gain chip and extended silicon nitride bragg grating. 50 khz absolute linewidth with options to achieve hertz level linewidth via an external ultra stable reference.

Its unique temperature control and anti vibration design eliminates impact of changing external temperature and vibration thus achieving a stable. The highfinesse linewidth analyzers are high end optical instruments for measuring analyzing and controlling frequency and intensity noise of laser light sources. Considerations with respect to system level lidar constraints for use on mobile army. The built in sharp edged frequency discriminator significantly reduces linewidth while maintaining single mode operation across the full operating.

Ultra narrow linewidths from. The purespectrum nll is an ultra low noise narrow linewidth semiconductor dfb laser for optical sensing applications like lidar and rf over fiber. The uniquely designed ultra narrow fiber filter ensures single frequency operation of the laser. Fabricated ultra low κ bragg gratings provide a narrow bandwidth and high side lobe suppression ratio.

There is a need to develop more accurate methods to characterize ultra narrow laser linewidth and frequency noises.
