Where to Buy Single-frequency Lasers

Frankfurt Laser Company offers various kinds of wavelength-stabilized laser diodes. Those based on DFB or DBR lasers exhibit single-frequency operation.

CNI offers single-frequency lasers with wavelengths from the UV to the infrared region. They are widely used in many scientific and industrial applications. The spectral linewidth can be less than 0.00001 nm.

CNI successfully provided custom made lasers for 670.776 nm, 589.159 nm, 589.756 nm and even Q-switched SLM lasers to customers. The frequency drift over 8 hours was <200 MHz.

Eblana Photonics Discrete-Mode technology platform delivers unrivalled wavelength uniformity and stability which is critical for many scientific and industrial applications. Eblana’s DM laser exhibit high SMSR and excellent tuning performance over a wide wavelength range, with products available from 650 nm – 2400 nm.

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.

RPMC offers a wide range of single-frequency lasers, exhibiting narrow linewidths, with wavelengths from 349 nm to 16 μm. These offerings include DFB and DBR diode lasers, external cavity VBG diode lasers, fiber lasers, and DPSS lasers, available with both free-space and fiber-coupled output, and many packaging options including TO Can, butterfly, HHL, OEM modules, and turnkey packages.

HÜBNER Photonics offer single frequency lasers based on diode pumped solid state technology (DPSS) in the Cobolt 04-01, 05-01 and 08-01 Series. In addition to the single frequency, all lasers have excellent wavelength stability and accuracy as well as power stability. Ideal for any application needing a highly coherent light source.

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.

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.

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 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.

ALPHALAS offers CW or pulsed single-frequency lasers (single longitudinal mode) with TEM₀₀ beam profile at most of the standard laser wavelengths. Various proprietary and standard technologies including monolithic non-planar ring oscillators (NPRO), DFB and unidirectional ring laser designs are used to achieve stable single-frequency operation with a very low intensity noise. The output power in CW mode ranges from several tens of mW to > 10 W at 1030 nm and 1064 nm. The single-frequency Q-switched lasers offer the unique combination of very narrow spectrum (transform-limited pulses) with very low amplitude noise due to the absence of mode beating.

Applications include high-resolution spectroscopy, interferometry, holography, optical metrology, meteorology, efficient Brillouin- and Raman-shifted generation, Raman spectroscopy and optical trapping, to mention just a few of them.

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.
