摘要：
The two photon absorption (TPA), TPA induced frequency up conversion emission, and two photon pumped (TPP) frequency up conversion lasing properties of a new synthesized dye Trans 4 [p (N,N diethylamino)styryl] N methylpyridinium iodide (DEASPI) were experimentally studied. This new dye has a moderate TPA cross section of σ 2=6.9×10 -48 cm 4·s/photon at 1064 nm, but exhibits a high lasing efficiency. The overall superradiant lasing conversion efficiency is as high as 10.7% at the pump energy of 2.14 mJ.
