Deciphering the Nd3+ environment and energy-transfer mechanisms in thermally stable novel calcium aluminate glasses: elucidation of broadband high-gain performance for laser applications

“…From the F-L equation, it can be seen that the σ em value is directly proportional to the fourth power of λ p and is inversely proportional to the ∆λ eff . It has been observed that the redshift in λ p always causes an increase in ∆λ eff in the 1.06 µm emission of Nd, hence restricting the larger σ em value to attain [47]. Therefore, it is important to optimize the λ p and ∆λ eff values to maximize the emission cross section of a particular host.…”

Study on influence of modifiers on structural and spectroscopic properties of Nd3+ doped different lithium tetra borate glasses

“…A large value of stimulated emission cross-section is a desired property for low threshold, high gain applications and high efficient laser. sEmission peak wavelengths (λ p ), effective bandwidths (Δυ eff ), peak stimulated emission cross-sections (σ p ), optical gain parameters (σ p × τ R ) and optical gain bandwidths (σ p × Δν eff ) of 1 mol% Nd 3+ doped lithium tetraborate glass matrices have been calculated using the standard equations and are tabulated in table 8 [45]. From the table is observed that among the four glass matrices (Li, Ba, Ca, Na) studied, LiBiNaTNd glass matrix shows higher emission cross section, while comparing of mixed modifiers, LiBiLiNaTNd shows higher emission cross section.…”

Saturated Emission States in Fluorescent Nanostructured Media: The Role of Competition between the Stimulated Emission and Radiation Losses in the Local Emitters of Fluorescence

“…Specification of the model parameters and for the studied R6G- and DCM-based systems was carried out using the results of preliminary experiments and datasets reported in the literature (see Table 2 ). In particular, a cross section of the stimulated emission can be obtained using the following expression [ 46 , 47 ] with further spectral averaging Here, is the characteristic time of the fluorescence decay. Figure 6 displays the recovered values of for the examined R6G- and DCM-based systems against the pump intensity.…”
