Introducing “StarBurst LGS” - A Breakthrough in Laser Guide Star Power and Precision
By combining LEOS' patented frequency doubling with MPBC's all-fiber Raman technology, this collaborative system achieves unmatched brightness with minimal telescope thermal footprint at 589 nm with an output power of >75 W.
Montreal, QC, Canada - July 26, 2026 — To meet the growing demand for sharper astronomical observations, next-generation adaptive optics require more powerful, stable, and efficient laser guide stars (LGS) to counter atmospheric blurring. Addressing this challenge, LEOS (Italy) and MPB Communications Inc. (Montreal), have combined forces in their development of StarBurst LGS - the next paradigm shift in adaptive optics.
The StarBurst LGS system delivers an impressive >75 W of output power at 589 nm.
For emerging applications, such as debris tracking and optical ground stations, using higher power excites more sodium atoms, creating a brighter artificial guide star and even allowing operation in daylight. A higher signal-to-noise ratio allows the Adaptive Optics (AO) sensors to measure and adapt to atmospheric turbulence with greater speed and accuracy.
A key innovation of the StarBurst LGS System is its patented non-resonant frequency doubler technology. Unlike conventional resonant cavity-based approaches, LEOS’ design eliminates the need for an optical cavity, significantly simplifying the frequency conversion process, especially when frequency chirping is implemented. This breakthrough architecture reduces stress on optical components, minimizes system complexity, and enhances long-term reliability.
Another key distinction of the StarBust LGS System is MPBC’s patented Remote Pump Architecture, allowing the electronics cabinet to be housed an unprecedented +30 meters away from the laser head. “This, combined with the compact laser head design, provides maximum installation flexibility for optical ground stations and astronomical telescopes,” explains Dr. Daoping Wei of MPB Communications Inc.
“Furthermore,” adds MPBC’s Dr. Wallace Clements, “our robust All-Fiber Raman Amplifier Architecture provides a permanently aligned optical path, providing an exceptionally stable amplification platform that requires no field intervention!”
Initial adaptive optics system testing with the StarBurst LGS system is scheduled for this 2026, with field deployments at select facilities planned shortly thereafter.
