Homogeneous linewidth
WebA homogeneous linewidth of 85.6±4.4kHz is reported in 60 nm Eu 3+ doped Y 2 O 3 nanocrystals at 1.3 K. This linewidth was measured by two-pulse photon echoes on … WebFor that purpose, the width was characterized by the effective linewidth and the full-width at half-maximum (FWHM). ... Since the 1970s, this technique is mainly employed to fabricate homogeneous preforms in the longitudinal direction. A variant is proposed here, by using two doping solutions and by applying a gradual time doping.

Homogeneous broadening is a type of emission spectrum broadening in which all atoms radiating from a specific level under consideration radiate with equal opportunity. If an optical emitter (e.g. an atom) shows homogeneous broadening, its spectral linewidth is its natural linewidth, with a … Meer weergeven Broadening in laser physics is a physical phenomenon that affects the spectroscopic line shape of the laser emission profile. The laser emission is due to the (excitation and subsequent) relaxation of a quantum system … Meer weergeven In a semiconductors, if all oscillations have the same eigenfrequency $${\displaystyle \omega _{0}}$$ and the broadening in the imaginary part of the dielectric function Meer weergeven • Homogeneity (physics) • Voigt profile • Spectral line shape Meer weergeven Web23 jul. 2024 · The properties of random lasing are investigated for bubble-structure (BS) dye-doped polymer random media in which non-scattering and no-gain regions are distributed.
