Distributed feedback (DFB) diode lasers are convenient, small footprint and robust single mode laser sources. DFB lasers have an emission linewidth in the MHz to several MHz range, which may be too large for some applications, such as cold atom physics, optical clocks, laser ranging, lidar or gas sensing... Control of the diode forward current allows for the control the frequency of the emitted laser beam. 
A simple experimental method for measuring the thermal sensitivity of single-mode fibers.
By measuring the intensity variations due to interference of light reflected from the fiber front and end surfaces, while ramping the ambient temperature, the thermal sensitivity of the optical-path length of the fiber can be derived and a simple fiber-interferometer, which is insensitive to thermal drifts, could be constructed.
Design of a Temperature Insensitive Fiber Interferometer for Long-Term Laser Frequency Stabilization using Metal Coated Fibers
This work presents the design for a temperature drift-free path imbalanced ber interferometer for long-term laser frequency stabilization using coated bers with different thermal drift. For this

Wideband tunable laser phase noise reduction using single sideband modulation in an electro-optical feed-forward scheme.
By placing the proposed phase noise reduction system after a commercial tunable laser, a tunable coherent light source with kilohertz linewidth over a tuning range of 1530-1570 nm is demonstrated.
Analysis of the feed-forward method for the referencing of a CW laser to a frequency comb.
Application of the feed-forward method to a distributed feedback diode laser at 1.55 μm allows line narrowing from 800 to 10 kHz, with frequency noise reduction by more than 2 decades up to a Fourier frequency of 100 kHz and a maximum control bandwidth of 0.8 MHz.
Direct frequency comb synthesis with arbitrary offset and shot-noise-limited phase noise
Scientists demonstrate a simple self-referenced feed-forward approach for stabilizing the carrier–envelope phase of femtosecond light pulses. Twelve attoseconds of residual timing jitter below the
Long-term carrier-envelope-phase-stable few-cycle pulses by use of the feed-forward method.
Pulse quality and power issues can be solved, leading to few-cycle pulses with good beam quality, and day-long CEP-stable operation of the setup is achieved.
