Where to Buy Narrow-linewidth Lasers

Edmund Optics offers narrow-linewidth lasers, e.g. in the form of metrology lasers with ±0.002 nm wavelength stability.

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.

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.

RPMC offers a wide range of narrow linewidth laser diodes and laser modules with wavelengths from 405 nm to 2 μm. These offerings include DFB and DBR diode lasers, external cavity VBG diode lasers, fiber lasers, and DPSS lasers. All are available in both OEM and turnkey packages.

All of TOPTICA’s tunable diode lasers offer a narrow linewidth of typically 100 kHz, corresponding to coherence lengths of almost 1 km. By stabilizing these lasers even further with TOPTICA’s locking electronics, linewidths below 1 Hz are possible.

Menlo Systems offers ultrastable, frequency stabilized lasers at basically any wavelength. We supply fully characterized systems with linewidths <1 Hz and Allan deviations of 2 × 10^-15 (in 1 s) as well as modules and components allowing for state-of-the-art systems tailored to your requirements.

Frankfurt Laser Company offers various kinds of wavelength-stabilized laser diodes which all exhibit a narrow emission linewidth. Those based on DFB or DBR lasers even exhibit single-frequency operation.

Laser Quantum offer a number of lasers with a narrow linewidth and high spectral purity, including the torus 532 and torus 660 mode-locked SLM lasers and the ventus solo, designed for high resolution Raman spectroscopy applications.

With the CVFL, CYFL and CEFL kilo models, Lumibird offers CW fiber lasers with very narrow linewidth down to 1 kHz. These single frequency lasers emits at 1054/1083 nm for the ytterbium version, in the 1.5-µm range for the erbium version and at frequency converted wavelengths for the CVFL model. These lasers are specifically designed for applications which requirehigh precision such as LIDAR, atomic spectroscopy, or atom cooling.
