From the project
Dual laster Pound-Dreaver-Hall driver setup. 1550 nm DFBs. Q=10^-5. Less than 20 GHz difference
A precision two-channel controller for 1550 nm DFB butterfly lasers — a differential optical thermometer built as a 3U Eurocard instrument.
Each channel provides low-noise constant-current laser drive, a bipolar linear TEC temperature controller, RF frequency modulation, and a synchronous-demodulation Pound–Drever–Hall lock that holds the laser to the side of an optical resonance. Lasers A and B lock to their own fringe of a shared reference cavity; the beat frequency between them, Δν = S·(TB − TA) with S ≈ 2 GHz/K, is a ratiometric measurement in which slow common-mode drift cancels.

AC Board: common questions
How big is the AC Board?
The AC Board measures 62.4 × 42.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the AC Board?
5 components, from 3 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the AC Board design files?
From the scular-HCC/DualLaserPDHDriver repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the AC Board design in my own project?
It is published under Custom license, which limits how it may be reused; read the license before building on it.
