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.
