Where to Buy Single-frequency Lasers

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.

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.

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

Our Koheras narrow linewidth, single-frequency fiber lasers are ultra-low noise sources. We have based these lasers on a DFB design to give you a robust and reliable operation. Koheras offers unprecedented low phase and intensity noise levels at rubidium, strontium, barium, and ytterbium wavelengths. It has high stability and mode-hop-free inherent single-frequency output – even when exposed to changing environmental conditions.

Almost every offered laser wavelength version has a narrow spectrum option, comes in the same compact MatchBox housing and provides the same wide range of selection for your configuration concerning the output types (MM/SM-PM fiber-options, SMA-connector) and power levels, internal temperature control and driver electronics inside of the laser’s housing. These lasers are essential for precise scientific applications, such as Raman spectroscopy or quantum cryptography. They can also be manufactured with clean-up filters inside the housing to improve the side-mode-suppression ratio. Passively Q-switched lasers are also available in narrow-linewidth versions.

AdValue Photonics has the AP-SF single-frequency fiber laser emitting in the 2-μm wavelength region with a linewidth around 10 kHz. The AP-SF1 is an amplified version with 5 W output power. Both come with a turn-key benchtop housing.

SHIPS TODAY: AeroDIODE offers fiber-coupled DFB laser diodes (1030 nm DFB, 1064 nm DFB, 1310 nm DFB, 1550 nm DFB or many other devices at a wavelength between 1250 nm and 1650 nm). They are offered as stock items or associated with a CW laser diode driver or pulsed laser diode driver. They are compatible with our high speed nanosecond pulsed drivers or low noise laser diode driver for single frequency emission. Typical narrow linewidth of a few tens of kHz are obtained with our dedicated ultra-low noise driver.

Eblana Photonics Discrete-Mode technology platform delivers unrivaled 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 – 12 μm.

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.

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.

QPC Lasers solutions include eye-safe MOPA diode lasers offering peak single-mode powers up to 100 W for applications including automotive LIDAR, Doppler anemometry and free space communications.

TOPTICA's single-frequency diode lasers employ state-of-the-art diode technology to achieve the highest single-frequency output power of any direct diode-based system. For example, the TopMode 405 nm model offers as much as 100 mW – an industry record!
