High Repetition Rate Pulse-Burst Laser and Camera for Energy Deposition Research

摘要: Abstract : Final Progress (1 Jun 02 30 Nov 03): A high speed camera and pulse-burst Nd:YAG laser system has been purchased as part of the DURIP equipment grant to be used for development novel diagnostic techniques research associated with energy deposition. This will allow a burst pulses (for diagnostics flow excitation utilizing deposition) subsequent imaging at MHz rates. Preliminary images DALSTAR 64K1M two Epix frame grabbing boards have taken flows induced breakdown in air arc/plasmas plumes test system. The custom built pulse designed, assembled initial performance evaluations completed. is initiated Lightwave cw diode pumped laser, chopped programmable Pockels cell Kentech shaper, amplified by five flashlamp from Quantronics-Continuum. can provide packet over 28 mJ separation variable one microsecond above. study deposition supersonic temporally resolved visualization quantitative techniques. developed applied current projects involving local control well other studies DOD interest.
