Laser Engineer - High-Power Fiber Lasers

Power the future of Space at Star Catcher

Star Catcher is building the first energy grid in space to power the orbital economy.

Today's spacecraft must generate all of their own power, which caps what they can do and how long they can operate. But what if they could "plug" into a grid, the way buildings do on Earth? Instead of cables and outlets, Star Catcher is building the technology to wirelessly beam energy to spacecraft's existing solar panels when and where they need it.

Be an early member of a team building an entirely new energy infrastructure at scale to power the next frontier.

Star Catcher Industries, Inc., located in Jacksonville, Florida, has an opportunity for a Laser Engineer - High-Power Fiber Lasers to support the development of space-to-space power beaming spacecraft and the Star Catcher Network, its orbital power grid.

Key Responsibilities

• Design and develop high-power, near-diffraction-limited (M² < 2) fiber laser sources and amplifiers for space-to-space laser power beaming.
• Define laser architecture and requirements with the senior laser engineer, including wavelength, output power, beam quality, linewidth, polarization, wall-plug and optical efficiency, thermal load, and reliability.
• Model laser and amplifier performance, including rate-equation gain and ASE, thermal effects, nonlinear thresholds (SBS, SRS, SPM), and transverse mode instability (TMI).
• Design and select components for high-power fiber lasers: gain and delivery fibers, pump diodes, pump/signal combiners, cladding light strippers, isolators, end caps, and wavelength combiners.
• Design, assemble, splice, and test high-power fiber lasers; establish characterization of power, spectrum, M², polarization, and stability.
• Develop non-standard sources where needed, such as thulium-doped fiber lasers near 0.8 µm, Raman fiber lasers, and frequency-doubled visible sources.
• Work with Electrical Engineering (laser-drive power electronics), thermal, and beam-expander teams on diode drivers, heat rejection in vacuum, output collimation, and beam delivery.
• Support the path to space qualification, including radiation-induced attenuation and photodarkening, thermal-vacuum and vibration performance, outgassing, and pump-diode reliability and derating.
• Support technicians in laser build practices, and manage technical relationships with fiber, diode, and component vendors.

Basic Qualifications

• Education: Bachelor's degree in Physics, Optical Engineering, Electrical Engineering, or a related technical discipline.
• Experience: 3+ years of hands-on experience designing, building, and testing high-power fiber lasers or amplifiers; candidates with more experience are preferred.

Technical Expertise

• Fiber laser and amplifier design, including rate-equation modeling and laser physics.
• High-power fiber laser physics: thermal effects, photodarkening, nonlinear effects (SBS, SRS, SPM), TMI, and their mitigation.
• Design and selection of components for kW-class fiber lasers, including large-mode-area fibers, pump combiners, and cladding light strippers.
• Hands-on fusion splicing of large-mode-area and specialty fibers, and assembly and test of high-power fiber lasers.
• Beam-quality, spectral, and power characterization (M², optical spectrum analyzers, power meters, beam profilers).
• Working knowledge of Class 4 laser safety practices.

Preferred Qualifications

• Space Lasers: Design or qualification of space-qualified lasers or amplifiers (strongly preferred).
• Non-Standard Wavelengths: Thulium, Raman, or frequency-doubled fiber sources.
• Power Scaling: Spectral or coherent beam combining, or narrow-linewidth amplifiers.
• Pump Diodes: Diode reliability, derating, and wavelength stabilization.
• Modeling Tools: RP Fiber Power or equivalent commercial or custom fiber laser models.
• Advanced Degrees: Master's degree or Ph.D. in Physics, Optics, or Laser Engineering.
