摘 要：We have observed degenerate and nondegenerate four-wave mixing in liquid crystalsMBBA and p-methoxybutyl oxyazobenzene in their isotropic phases（at temperatureshigher than 42℃and 70℃ respectively）.The expeinental setups are shown in *** *** 4 is the mixed *** mixing efficiency（intensityratio of beam 4 to beam 3）was about 2×10-3and 1×*** parametefor the SHG of YAG laser are as follows:wave length,5320（?）;pulse width,14ns;outputenergy,5-6mJ;cross-section of the beams,about 1 *** for the flash-lamp-pum-ped dye laser are:wavelength 5800（?）;pulse width,0.5μs;output energy,*** of the YAG laser and the dye laser output could be synchronized or adjusted tohave a relative *** angle between beams 1 and 3 was about 0.08 *** of the sample’s temperature was less than 0.01℃.
