Where to Buy Narrow-linewidth Lasers

For various applications like laser spectroscopy, optical metrology, optical sensors and holography one requires lasers emitting light with a very narrow linewidth, i.e., with high temporal coherence. They are usually single-frequency lasers. In extreme cases, sub-Hertz linewidth values are achieved.

narrow-linewidth lasers

The PureSpectrum™ NLL is an ultra-low-noise, narrow linewidth semiconductor DFB laser for optical sensing applications like lidar and RF over fiber. 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. The built-in, sharp-edged frequency discriminator significantly reduces linewidth while maintaining single-mode operation across the full operating temperature range. The model also offers fast frequency tuning, which enables frequency-modulated continuous-wave sensing.

narrow-linewidth lasers

The Koheras narrow linewidth, single-frequency fiber lasers are ultra-low noise sources with longitudinal single mode and single frequency operation. The lasers are based on a DFB design ensuring robust and reliable operation and are delivered as fully integrated systems for industrial and scientific applications. Koheras offers an unprecedented low phase- and intensity noise level at Yb, Er and Tm wavelengths. It has a very high stability, and mode-hop free inherent single frequency output – even when exposed to changing environmental conditions. You can also get shot noise limited solutions for applications demanding an extra low intensity noise level.
