- 13EarningsCOHRCoherent Q4 FY2026 earningsThe largest US-listed precision-photonics supplier with a dedicated quantum/cold-atom laser portfolio updates lasers-segment demand — and any commentary on Sapphire XT displacing AOM sockets reads directly on this chokepoint.
September 2026
- 30PolicyNational Quantum Initiative Reauthorization Act floor votes / enactment (S.3597 / H.R.8462)Both chambers' committees cleared the bill in April 2026; enactment extends the NQI through 2034 and funds the federal lab and program demand that flows straight to narrow-linewidth laser, AOM, and precision-optics suppliers.
December 2026
- 08EarningsGCHHFGooch & Housego FY2026 full-year resultsThe only listed near-pure proxy for AOM supply; order-book growth (record £167m at H1) and photonics lead-time commentary are the cleanest public read on whether this chokepoint is tightening.
- 15ProgramDARPA Quantum Benchmarking Initiative Stage C selection decisionsStage B (11 companies, began November 2025) is a yearlong evaluation feeding Stage C down-selects; only four of the eleven — IonQ, Quantinuum, Atom Computing, QuEra — are trapped-ion or neutral-atom machines, and those are the laser-hungry ones whose survival would ramp narrow-linewidth laser and AOM orders.
