BluGlass Limited has demonstrated a world-record performance for its single-mode gallium nitride (GaN) lasers, achieving 1,250 milliwatts of power from a single laser chip while maintaining single-spatial mode.  

The milestone surpasses the company’s previous record of 750 milliwatts, reported in January 2025, marking a 67 per cent performance increase, the company said in an ASX announcement.

The breakthrough was enabled by integrating a blue (450nm) single-mode laser master oscillator with a power amplifier into a single monolithic chip (SM-MOPA). 

According to BluGlass, this is the highest-known published result commercially and in academia. 

The enhanced power output is expected to advance applications in quantum sensing, defence, aviation, space communications, and underwater LiDAR.

“We have demonstrated the highest-known performing single-mode GaN laser in the world to date,” said BluGlass CEO Jim Haden. 

“These lasers pave the way for scaling power at high fidelity—producing stable laser beams that can be more easily and cost-effectively packaged to meet the demands of next-generation applications where precise and stable performance is essential.”

Haden highlighted that most high-powered visible lasers compromise beam quality to achieve greater power. 

“Our advanced integration capabilities will enable industry to pioneer innovations by increasing power without sacrificing precision and beam stability,” he said. 

“We achieved these world-leading results by combining our blue single-mode laser with a power amplifier that boosts the laser’s power with minimal beam distortion or increase in noise.”

BluGlass has also significantly improved the power output of its distributed feedback (DFB) family of devices, increasing from 100 milliwatts to 450 milliwatts while maintaining near single-frequency output and a high side-mode suppression ratio. 

This was achieved using a blue (450nm) single-mode DFB laser with an integrated master oscillator power amplifier in a single monolithic chip (DFB-MOPA). 

The company noted that its GaN DFB lasers are being designed for wafer-scale fabrication to enhance production volume, reduce optical complexity, and lower costs, particularly for quantum technologies and computing.

“Our strategic focus on scaling power at high fidelity for the precision market—amplified single-mode and DFB lasers—has led to this world-record single-mode visible power and the quadrupling of power in our narrow linewidth lasers,” Haden added. 

“Our ability to satisfy unmet market needs is why BluGlass continues to be selected as a partner of choice by industry leaders, including the US Department of Defense’s Microelectronics Commons.”
