We have investigated the stimulated emission properties of Nd(3+) doped La(2)O(2)S powders at room temperature as a function of pumping energy density, excitation wavelength, and Nd(3+) ion concentration. The absolute stimulated emission energy has been measured. Expressions for the slope efficiencies and lasing thresholds as a function of rare earth concentration and pumping wavelengths, which...
LASER is an acronym of light amplification by stimulated emission radiation. A beam passes through a specific medium stimulating the atoms within and following direction, direction with wavelength original beam.
To achieve population inversion an EDFA uses stimulated emission process where incident photon and emitted photon have same phase. But, alongwith the stimulated emission that creates gain, the gain medium also produces spontaneous emission, which gives rise to the amplified spontaneous emission (ASE) spectrum of the amplifier []. In this paper we have considered the setup to measure amplified s...
