Where to Buy Distributed Feedback Lasers

TOPTICA’s DLC DFB pro lasers integrate both distributed-feedback (DFB) and distributed Bragg reflector (DBR) lasers. Available wavelengths include 633 nm and the entire range from 760 nm to 3500 nm. Three laser heads accommodate different diode packages. Due to the absence of alignment-sensitive components, the DLC DFB pro lasers exhibit an exceptional stability and reliability.

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.

Distributed feedback lasers (DFB lasers) simultaneously provide smooth, tunable control of wavelength and the extremely narrow spectral width required for precise fiber optic communication and spectroscopy applications. Integrated modules provide further narrowing of the spectral line in a compact OEM package that features simple tuning interface.

G&H offers a broad range of DFB lasers in the C-band and L-band on 50 or 100 GHz channel spacing as well as at 1310 nm, 1064 nm, and custom wavelengths. Power level options include 40–100 mW out of the fiber for high power 14-pin lasers and 10-18 mW options for high bandwidth 7-pin configurations.

APIC has developed very low noise (RIN) DFB lasers in the 1550 nm wavelength range with models that perform direct modulation (DML) up to 6 GHz and continuous wave (CW) lasers.

The DML laser come in a variety of optical power outputs from 10 to 40 mW with RIN between -160 and -155 dB/Hz.

The analog/CW lasers have optical power output levels between 40 and 120 mW with RIN between -170 to -160 dB/Hz; some models maintain low RIN out to 20 GHz.

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.
