BluGlass gets repeat order for GaN laser bars
Australian laser company BluGlass has received an order of around $76k for semi-custom GaN laser diode bar products, from the College of Optics and Photonics (CREOL), University of Central Florida, and a repeat customer.
The order follows the university's successful demonstration of significant performance improvements using BluGlass’ specialised GaN laser bars in a Coherent Beam Combining (CBC) array. The work 'Coherence and Phase-Locking in High-power, Broad-Area, Highly Heterogeneous Blue Diode Arrays' appeared in ACS Photonics, on January 8th 2025.
BluGlass says its semi-custom designs show superior coherence and phase locking in high-power blue laser arrays, demonstrating improved performance and precision, compared to commercially available laser bars.
The CBC configuration merges light emitted from an array of broad linewidth multi-mode lasers into a high-power single-mode, narrow linewidth, coherent beam. This technique allows the customer to produce powerful, high quality blue laser beams that phase stability, and narrow line widths - critical for next-generation technologies, including underwater and aviation LiDAR systems that map the seafloor or monitor clear air turbulence, advanced space research and communications, and ultra-sensitive quantum sensors.
T CEO Jim Haden said: “This repeat order validates the exceptional performance of our custom GaN laser technology, demonstrating our ability to help customers solve critical challenges and pioneer next-generation visible laser applications. High-power coherent GaN lasers can transform defence and dual-use capabilities from secure underwater communications and imaging, and clear-air turbulence monitoring in atmospheric LiDAR, to countermeasures and jamming systems that disrupt enemy optics with high-intensity beams.
“These performance advantages help position the company for future growth, and building on this success, we will leverage our partnership with this leading university to pursue critical defence applications that require the superior coherence, stability, and precision of BluGlass’ GaN lasers.”
