The first one is a laser rainbow, a multiple co-axial ring Stokes Raman emission by four-wave mixing parametric processes, and the second one is the self-trapping (filamentation) of the propagating laser pump beam and Stokes generation. 关键词: AOT; HEPTANE; MICROEMULSION; NANOPARTICLES; PALLADIUM; TERNARY SYSTEM; WATER WATER;
