| Abstract: | The efficiency of some organic compounds as frequency-doubling materials
was determined using Kurtz-Perry powder technique. Compounds were sieve graded
to desired particle size before testing their second-harmonic generation (SHG)
efficiency. A pulse from a Nd:YAG laser at 1.064  m was used to examine the
efficiency of the material. Effect of particle size on SHG efficiency was
studied and showed that the crystalline materials were phase-matchable at
certain wavelengths. The intensity of the frequency-doubled output at 532 nm
was measured and the second harmonic generation efficiencies obtained were
compared with those of standard SHG materials, and other compounds. Comparison
showed that the SHG efficiencies of some of the compounds studied here are
several orders of magnitude greater than those of known standard materials and
substantially higher than other reported compounds. |
