FIG. 1.

(a) Molecular structure of PFC. (b) Emission spectra from PFC films under different excitation fluences (from bottom to top: 0.2, 0.4, 0.9, 2.5, 4.2, 5.1, 6.2, and ).

FIG. 2.

Dependence of the ASE integrated emitted intensity (solid circles, left scale) and spectral width [full width at half maximum (FWHM), open circles, right scale] on the pump energy density. The continuous line is the best fit to the data up to by an exponential-like ASE model. The dotted line is the best fit of the data between and to the square root behavior predicted by the bimolecular annihilation model. The dashed curve interpolating the FWHM data is a guide for the eyes only.

FIG. 3.

Emission spectra by different excitation length: 1.07 (a), 2.39 (b), 3.71 (c), 5.03 (d), 6.78 (e), 7.66 (f), and 8.54 mm (g).

Optical gain spectrum for an excitation density of . The continuous line is a guide for the eyes. Inset: FWHM vs excitation length.

Image of FIG. 5.
FIG. 5.

Dependence of the ASE output from the slab edge on the length of the nonexcited region between the pump stripe and the edge of the sample. The dotted line is the best fit of the data to the equation .
