About the role
- With the use and commercialization of laser-induced inertial fusion, a clean and highly efficient power generation technology is coming within reach, suitable to ensure a secure and scalable future energy supply.
- Focused Energy is an equal opportunity employer committed to creating an inclusive environment.
Responsibilities
- Diode Technology Development: Design and evaluate high-power laser diode emitters, bars, and stacks to meet demanding performance, efficiency, lifetime, and cost targets for fusion laser applications.
- Testing & Characterization: Develop and execute comprehensive electro-optical, thermal, and reliability test protocols (P-I-V, spectral behavior, beam quality, thermal resistance, lifetime, etc.) under relevant operating conditions including pulsed, CW, and high-duty-cycle regimes.
- Automated Test Infrastructure: Design, commission, and operate automated test benches for high-volume characterization and accelerated life testing of commercial and custom laser diode devices.
- Reliability & Lifetime Modeling: Lead accelerated life testing (ALT / HALT), analyze degradation mechanisms and failure modes, and build predictive lifetime and reliability models to inform system design and operational limits.
- Supplier & Partner Collaboration: Work closely with industry partners, suppliers, national labs, and academic groups to improve diode performance, packaging, thermal management, and manufacturing readiness.
- System Integration: Collaborate with DPSSL system and beamline teams to ensure diode technologies integrate effectively into laser modules and support overall system performance and scalability.
- Data Analysis & Reporting: Analyze large experimental datasets, generate rigorous technical documentation, and communicate findings and recommendations clearly to internal teams and external partners.
- Proven experience designing, building, and operating laser diode test and characterization setups, including optical, thermal, and electrical diagnostics.
- Able to work effectively across internal system teams and with external suppliers, academic collaborators, and industrial partners in complex, multi-stakeholder environments.
- Design and evaluate high-power laser diode emitters, bars, and stacks to meet demanding performance, efficiency, lifetime, and cost targets for fusion laser applications.
Requirements
- PhD (or equivalent experience) in optical, electrical, mechanical engineering, physics, or a related field, with deep experience in semiconductor laser physics, epitaxy, packaging, and/or device characterization.
- Strong understanding of thermal management, reliability physics, degradation mechanisms, and lifetime testing methodologies for high-power semiconductor devices.
Nice to have
- Experience working with diode-pumped solid-state lasers (DPSSL), high-average-power laser systems, or adjacent fields such as industrial lasers, photonics manufacturing, or fusion/energy systems.
- Experience with thermal, optical, or reliability modeling tools to complement experimental work and support predictive design and scaling.
- Preferred: Experience working with diode-pumped solid-state lasers (DPSSL), high-average-power laser systems, or adjacent fields such as industrial lasers, photonics manufacturing, or fusion/energy systems.
- Preferred: Experience with thermal, optical, or reliability modeling tools to complement experimental work and support predictive design and scaling.
