1 Raydiance Proprietary: Do not Distribute Without Permission Desktop Ultra-Short Pulse Laser at 1552 nm Ultrashort Pulse Laser Materials Interaction Workshop DIRECTED ENERGY PROFESSIONAL SOCIETY (DEPS) L. Vaissié, T. Yilmaz, A. Stadler, D. Goldman, M. Farley, J. Lammers, T. Saunders, K. Kim, D. Lijana, L. Collura, M. Mielke, & T. Booth

2 Raydiance Proprietary: Do not Distribute Without Permission 2 UltraShort Pulse (USP) Lasers Long Pulse or CW Lasers USP Lasers Metal ablation with femtosecond (right) vs. nanosecond (left) ablation.

3 Raydiance Proprietary: Do not Distribute Without Permission 3 UltraShort Pulse (USP) Lasers Immense power in each pulse Non-thermal, precision ablation Little or no trauma/damage to remaining material Ablates any material Diagnostics, sensing, other non-ablative properties One source, many uses

4 Raydiance Proprietary: Do not Distribute Without Permission 4 Interesting capabilities, but impractical Compelling Capabilities, but… Experimentation and Exploration are Difficult Requires Ph.D.’s to operate and maintain Very Expensive Impractical/Impossible to Deploy

5 Raydiance Proprietary: Do not Distribute Without Permission 5 Until Raydiance… We took complicated apparatus and turned it into this: Pulse width: < 3 ps M 2 < 1.8 Average Power: 2.5 W Any room, 110 v outlet (800 W) Pulse energy: 1 to 5 µJ Wavelength: µm Pulse rate: 25 kHz kHz

6 Raydiance Proprietary: Do not Distribute Without Permission 6 Classic CPA Approach 1ns ~500 fs 1ns ~ 850fs 5  J Modelocked Diode Laser Pulse Stretcher Pulse Compressor High Power Amplifier Mostly fiber-based components High power, dispersion and nonlinearity managed miniature optical network

7 Raydiance Proprietary: Do not Distribute Without Permission 7 Fiber & Integrated Hardware Use off-the-shelf fiber optics for seed & pre-amp stages Team with strategic partners for subassemblies Build what we can’t buy There are constraints… Peak power density very high in fiber Operation near damage threshold Optical nonlinearities Novel fibers require special attention Multimode effects Parasitic energy losses due to high dopant levels

8 Raydiance Proprietary: Do not Distribute Without Permission 8 Raydiance User Interface (UI)

9 Raydiance Proprietary: Do not Distribute Without Permission 9 Desktop USP System Pulse Quality Intensity AutocorrelationIntegrated Energy

10 Raydiance Proprietary: Do not Distribute Without Permission 10 Further Signal Quality Data Retrieved from FROG E-field FWHM: 843 fs AC FWHM: 1.3 ps
