Brightlaser is pleased to introduce our upgraded 852±1nm polarization-stable single-mode VCSELs, developed for advanced sensing applications. Engineered for quantum magnetometers and Cesium D2 (852.35nm) atomic clocks - and equally suited for high-resolution LiDAR/OCT - these devices deliver the precision, coherence, and stability required in demanding quantum systems.

Key Single-Mode Advantages:

• Precision & Coherence:

Precisely aligned to 852.35nm with an ultra-narrow linewidth (<100 MHz).

• Outstanding Stability:

>20 dB polarization extinction ratio (PER) and >35 dB SMSR for clean, reliable output.

• Optimized Optical Performance:

Typical 2 mW output with a circular, highly collimated Gaussian beam profile.

• SWaP-Efficient Operation:

High-speed modulation up to 100 kHz and >8 nm mode-hop-free current tuning at ultra-low power.

• Flexible Packaging Options:

Available in SMD, SMD with collimation lens, TO packages (with or without TEC), and fiber-coupled configurations.

Please refer to the attached leaflet for detailed optical spectra and modulation characteristics. We would welcome the opportunity to discuss how these VCSELs can support your next-generation sensing designs or to arrange samples for evaluation.

We understand that each project has unique demands, which is why we provide customized VCSEL solutions tailored to your specific application. Whether it's wavelength and power output, form factor, or packaging options, we ensure a personalized solution that precisely meets your needs.
