Includes bibliographical references
The month has been spent in a series of harmonic generation experiments at increasing peak intensity and fluence. Second harmonic beam quality has been measured. Using the oscillator alone, with grating selection of the 9.55 micrometer line, the pulse train consisted of a spike containing about 10 pulses followed by a tail containing about 40 pulses. Both the spike and the tail contained approximately equal energy, the combined total going as high as 180 mJ. The crystal was located near to the plane exit mirror of the oscillator, where the near-parallel beam has a Gaussian (amplitude) spot parameter of 0.46 cm. The on-axis fluence was 0.5 J/sq. cm. and the peak intensity in the 2 nsec optical pulses was approximately 20 NW/sq. cm. The pulses were separated by 40 nsec. Energy conversion efficiency of up to 31% was recorded, with 56 mJ of second harmonic (outside the crystal) for 181 mJ of incident 9.55 micrometer radiation. The second harmonic energy depended on the 1.5 power of the fundamental in the fundamental energy range 50 mJ to 180 mJ. Time-dependent analysis showed that the conversion efficiency was close to 50% in the spike but generally less than 10% in the 'tail' as expected from their intensity ratio (in the range 4:1 to 8:1)
