  1. Data Acquisition using the Arduino Microcontroller TakakoHirokawa

  2. Intro to Ultrafast Optics • Early ultrafast optics • Short exposures • Power =100 GW • Intensity = 1017 W/cm2 • E-field = 3x1012 V/m 1 mJ 10 fs

  3. What is HHG? • Intense laser pulse (~1014W/cm2) • Gas jet in vacuum

  4. Ionization 3 three step model Schafer, Yang, DiMauro, Kulander, Phys. Rev. Lett. 70, 1599 (1993) Kulander, Schafer, Krause, Laser Physics 3, 359 (1993) Corkum, Phys. Rev. Lett. 71, 1994 (1993) time e- E-Field

  5. Acceleration 3 three step model time E-Field

  6. Recombination 3 three step model Ephoton=Ekin+IP time E-Field

  7. Setup HH13 25

  8. The Arduino

  9. Demonstration!

  10. Results • How effective? • Flexible • User-friendly • Cost-effective • Use this parameter data (e.g. pressure) to see how the harmonics correlate.

  11. Pressure Curve

  12. Next Steps • For the lab: • The Arduino can control other components in the lab • The Arduino can control an entire experiment.

  13. Thank you! • My mentors, Markus and Brian, as well as Joe and the rest of the Bucksbaum group for an awesome summer. • DOE and SLAC for this amazing opportunity. • Steve Rock for his dedication to the program.
