| Abstract: | Double-pulse laser controlling method used for film cooling holes processing of aircraft engine turbine blade is studied.Double-pulse laser experimental results of producing approximately 100 ns temporal delay between the pulses with polarization beam combining by two sets of flash-lamp pumped electrooptical Q-switched laser are reported.The interval of co-aligned double-pulse laser can be turned freely from 0 to several hundred nanoseconds.The maximal timing jitter of double-pulse laser is less than 5 ns.T... |
