Description

The ML6645 series is Modulight’s next‑generation VECSEL laser source family, built on the proven ML6600 platform and engineered to deliver exceptional performance across multimode, single‑mode, and single‑frequency operation. Offering access to wavelengths spanning 460–630 nm—including key yellow‑orange lines such as 572, 578, 589, and 614 nm—the ML6645 closes the long‑standing “yellow–orange gap” with reliable multi‑watt output power and excellent beam quality.

Powered by Modulight’s in‑house VECSEL technology, the ML6645 combines low‑noise operation, configurable linewidth, precise tunability, and high stability. Multimode versions deliver high optical power with uniform beam profiles for illumination, dermatology, and projection applications. Single‑mode variants offer diffraction‑limited beam quality, several watts of output power, and high spatial coherence well suited for microscopy, flow cytometry, sequencing, and other precision life‑science applications. For the most demanding use cases, single‑frequency models provide ultra‑narrow linewidths, high power stability, and exceptional wavelength purity for quantum technologies, metrology, and precision spectroscopy.

Thanks to the modular ML6600 architecture, the ML6645 supports CW, QCW, and microsecond‑to‑continuous modulation modes as well as a broad 5–100% dynamic output‑power range. The system features a user‑friendly interface with RS232/RS422 connectivity and Python‑compatible SDK for seamless integration into laboratory and OEM platforms. Robust mechanical design, ceramic baseplates in single‑frequency models, optimized thermal management, and fast warm‑up times ensure long‑term stability even in demanding environments.

With wavelength flexibility, powerful tuning options, and operation modes tailored for everything from high‑throughput illumination to high‑precision atomic transitions, the ML6645 sets a new standard for advanced applications in life sciences, medical diagnostics, quantum technologies, spectroscopy, astronomy, and photonics research.
