Where to Buy Single-frequency Lasers

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.

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.

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.

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.

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

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.

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.

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.
