13. 2. The 1064 nm fundamental was produced by a Molectron MY34-20 Q-switched Nd:YAG laser with a 20 ns pulse width operating at a 20 Hz repetition rate. The second harmonic signal at 532 nm was sent through an analyzer and separated from the fundamental via a series of green pass filters and an Instruments SA, Inc. DH-10 double monochromator. The 532 nm light was collected in a Hamamatsu R1477 photomultiplier tube, and the signal was sent out to a Stanford Research Boxcar Averager and then to the digital data acquisition system and an oscilloscope. All data were corrected for transmission of the fundamental and absorption of the second harmonic, and a 3 mm thick single quartz crystal served as a reference.
