BluGlass Smashes Its Own World Record With 52% Leap in Laser Output Power
BluGlass breaks its own world record with 1.9W single-mode GaN laser output
BluGlass Limited (ASX: BLG) has set a new world record for single spatial mode GaN laser output power, achieving 1.9W peak from a single monolithic chip at 450nm. The result represents a 52% improvement over the company’s own previous world record of 1.25W, underscoring sustained technical momentum rather than a one-off achievement.
The milestone was delivered through BluGlass’ proprietary MOPA architecture, combining a master oscillator and tapered power amplifier on a single chip. The result directly supports the company’s US$100 million development pipeline and customer conversion progress across defence, quantum, and advanced industrial programs.
CEO Commentary
“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.”
Jim Haden, Chief Executive Officer and Executive Director, BluGlass Limited

What is a GaN MOPA laser and why does this record matter?
The technology explained
Gallium nitride (GaN) lasers are semiconductor light sources that emit in the visible spectrum, particularly in the blue wavelength range. Unlike raw power output alone, single spatial mode operation refers to the laser maintaining a precisely controlled, single-point beam profile, which determines beam quality and is critical for applications that require pinpoint accuracy, such as quantum sensing and directed energy.
Scaling power while preserving single spatial mode is technically demanding. As output increases, beam quality typically degrades, making high-power single-mode performance a genuine engineering challenge rather than a straightforward incremental improvement.
BluGlass addresses this through its MOPA architecture. The master oscillator generates a precise, high-quality beam, while the tapered power amplifier boosts output power. Independent electrical control of both sections allows simultaneous optimisation of gain and beam quality, a capability that is central to the company’s competitive differentiation in gain-chip technology.
Why 1.9W in a single chip is significant
The technical achievement encompasses several attributes that matter to both commercial and government customers:
- 1.9W continuous amplified peak power from a single monolithic chip
- Stable single-spatial mode emission maintained at peak power
- Well-defined far-field beam profile confirming beam quality preservation
- 450nm blue wavelength, critical for defence, quantum sensing, and industrial use cases
| Metric | Previous Record | New Record | Improvement |
|---|---|---|---|
| Peak Output Power | 1.25W | 1.9W | +52% |
| Architecture | MOPA | MOPA | — |
| Wavelength | 450nm | 450nm | — |
| Beam Mode | Single spatial | Single spatial | Maintained |
The world-record status has been validated through literature searches conducted by the University of California, Santa Barbara (UCSB) in conjunction with BluGlass, covering published research from 1900 through 2025.

From world record to commercial outcomes
Strengthening a US$100 million pipeline
This technical milestone is not an isolated laboratory result. According to management, it directly supports BluGlass’ expanding portfolio of customer and government development programs, with CEO Jim Haden explicitly connecting performance advances to pipeline conversion.
The company’s Tier 1 and government customers operate in sectors where laser specifications are exacting and supplier capability is a genuine barrier to entry. Advancements in design and fabrication over the past year have delivered the step-up in output power required to address those requirements.
Target sectors include defence, aerospace, quantum, and advanced industrial applications. BluGlass is positioned as a supplier to both established commercial customers and sovereign government programs, with its end-to-end manufacturing capabilities spanning epitaxy, device design, fabrication, and testing across operations in Australia and the USA.
CEO Commentary
“GaN lasers are critical to both established and emerging photonics applications, and our world-leading gain chips create a long-term opportunity for BluGlass to capture market share as next-generation technologies are developed.”
Jim Haden, Chief Executive Officer and Executive Director, BluGlass Limited
Where BluGlass is headed next
Management outlined a forward roadmap across several development priorities:
- Continued investment in MOPA architecture optimisation and epitaxial design improvements
- Broadening the wavelength offering beyond 450nm
- Further improvements to power output, efficiency, and reliability
- Early-stage engagements in surface-emitting architectures targeting AI data centres
- Next-generation sensing platform proposals in progress
The company’s sovereign supply chain positioning adds further strategic context. BluGlass is one of a small number of end-to-end GaN laser manufacturers globally, with vertically integrated capabilities that span from raw epitaxial growth through to finished laser products. That combination of technical leadership and manufacturing self-sufficiency places the company in a distinct position as governments and Tier 1 customers increasingly prioritise supply chain security for critical photonics components.
Pipeline conversion remains in progress, and management’s commentary reflects confidence in the commercial direction without overstating outcomes already secured.
