Effective control over the dual-color emitted light waves from one-dimensional random media pumped by Femtosecond-Lasing Pulses

摘要: The spectral property of dual-color random laser is investigated by simultaneously solving Maxwell’s equations and rate electronic population in which the pumping described a time function with duration hundreds femtoseconds. Results show that delay peak intensity emitted light depends strongly on process. An effective optimization method proposed to exercise control over emission from dye solution scattering nano-particles. It demonstrated numerically controllable single mode operation choosing proper pump profile region. present work enriches knowledge about lasers offers more guidance for relevant experiments.
