Where to Buy Single-frequency 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.

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.

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.

MPBC single-frequency fiber lasers are sources of single-frequency polarized light offering low phase and intensity noise, narrow spectral linewidth and long coherence length. They are comprised of a single-frequency near-infrared Yb-doped fiber laser with a single-mode narrow-band output and electronics which provide temperature stabilization as well as active stabilization of the laser output power. Available in the NIR at 1028 and 1064 nm with output power up to 10 W, or in the visible at 514 nm and 532 nm with 200, 500 or 1000 mW of output power.

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.

The HI-Q™ Laser houses a proprietary driver/controller and the OEwaves laser source, which is based on a high quality factor (Q) Whispering Gallery Mode (WGM) micro-resonator. The laser is scalable to a variety of wavelengths in 370-–4500 nm.

The unique technology of the OEwaves HI-Q™ Laser leverages the self-injection on locking of a suitable commercially available laser diode via a resonant optical feedback from a high-Q WGM micro-resonator. Its monolithically integrated approach along with micro-scale mass and volume make the laser virtually insensitive to environmental vibrations .
