Scientific papers / #TailoredLaser, 780 nm, 795 nm, butterfly, D1, D2, DBR, ICP, magnetometry, MOPA, narrow linewidth, quantum, Quantum West, sensing, SPIE, tapered amplifier / March 5, 2026

High-power narrow-linewidth lasers around 795 nm are essential for quantum sensing, magnetometry, Raman spectroscopy, and biomedical applications. This work introduces a fully integrated butterfly-packaged MOPA solution combining a sub-500 kHz DBR seed laser with a tapered amplifier to achieve watt-class output power while preserving spectral purity. The compact architecture enables high performance in a practical form factor suitable for demanding field and laboratory applications.

VCSELs for quantum sensing with Rubidium

Scientific papers / #TailoredLaser, 780 nm, 795 nm, array, chip-on-submount, OPTO, Rb, Rubidium, semiconductor, sensing, SPIE, VCSEL / March 5, 2026

Quantum computing platforms based on trapped ions and neutral atoms require robust, high-power laser systems across multiple wavelengths. This paper presents Modulight’s next-generation single-frequency VECSEL platform, delivering tens of watts of narrow-linewidth output with improved size, weight, power, and environmental stability characteristics. The architecture supports multiple integrated laser cores and wavelengths within a single system, providing a scalable solution for future quantum computing applications.
