BluGlass achieves record single-mode GaN laser performance
BluGlass has demonstrated a new world-record GaN laser single-mode performance – achieving 1.9W of peak output power from a single spatial mode laser. This milestone represents a 52 percent improvement over BluGlass’ previous world-record performance of 1.25W of single-spatial mode power.
The record achievement combined a high-performance 450nm single-mode GaN laser with the company’s proprietary gain-chip technology; incorporating a single-mode master oscillator with a tapered power amplifier (MOPA) to scale high-power while maintaining high-precision.
BluGlass’ unique GaN gain chips and novel MOPA architectures provide independent electrical control of the laser and amplifier, enabling optimisation of gain and beam quality. Testing confirmed 1.9W of continuous amplified peak power, maintaining stable single-spatial mode emission with a well-defined beam profile and preservation of beam quality at high-power.
BluGlass CEO and executive director Jim Haden said, “Our latest performance milestone highlights the strong technical progress our team continues to make advancing high-power, single-mode GaN lasers to support next-generation quantum and defence applications. Advancements in design and fabrication over the past year have delivered a significant step-up in output power to address the most exacting requirements of our Tier 1 and government customers.
“These capability advances support BluGlass’ growing commercial momentum and the ongoing conversion of our $100 million development pipeline as we turn technical innovation into customer-focused performance outcomes."
