Job Description
We are seeking an experienced engineer to drive the development of advanced high energy laser systems using coherent beam combining techniques. The Laser Engineer will enhance BLF’s laser-OEC concept by:
- Developing CBC laser sources with increased input power
- Developing active optical, mechanical, and feedbacking elements to maintain resonance
- Work with laser and fiber amplifier vendors to develop and procure optimal sources
- Modeling optical performance of the laser-enhancement cavity using industry-standard software
- Assessing thermal effects at higher input powers
- Troubleshooting and optimizing system performance
The BLF laser-optical enhancement cavity platform utilizes a Fabry-Pérot cavity to stack and store a train of lower power pulses into kJ+ high-energy pulses. This system requires:
- Ultra-high reflectivity mirrors
- Pulsed, high power laser injection
- High finesse cavities up to 150m in length
- Precise resonance tuning between the input laser and the cavity
- Minimization of optical losses
Qualifications
- MS/Ph.D. in Physics, Mechanical Engineering, or related field with a relation to fusion.
- Strong background in relatable mechanical engineering
- Demonstrated ability to work effectively in a collaborative team environment.
- Excellent written and verbal communication skills.
- Hands-on experience with mechanical design of relatable systems
- Ability to prioritize tasks and manage time effectively in a fast-paced research environment
- Comfort with working on new technologies with tbd best practices and design rules
- 3D printing skills
On-site Work:
