Line shapes of the giant two-photon absorption (GTA) band for the directgeneration of excitonic molecules (EM) and the subsequent secondary omissionof the EM resonantly generated have been studied in Curl at various pumppowers with the use of a high resolution spectroscopic method. The mutualcollision of the EM, the ratc of which is nearly proportional to their density, isfound to be the main origin for causing the broadening of the GTA band, thedecrease of the Raman yield and the rapid increase of the EM luminescence.The collision rate increases up to 10"/sec for the pump power of - 1 MW/cm'.With the tuse of pump and probe method further evidence is obtained for theeffectiveness of the mutual collision of the EM.
