Superconducting gap in BaFe$_{2}$(As$_{1-x}$P$_{x}$)$_{2}$ from temperature dependent transient optical reflectivity

Temperature and fluence dependence of the 1.55-eV optical transient reflectivity in BaFe $_{2}$ (As $_{1 - x}$ P $_{x}$ ) $_{2}$ was measured and analysed in the low and high excitation density limit. The effective magnitude of the superconducting gap of $\sim 5$ meV obtained from the low-fluence-data bottleneck model fit is consistent with the ARPES results for the $γ$ -hole Fermi surface. The superconducting-state nonthermal optical destruction energy was determined from the fluence dependent data. The in-plane optical destruction energy scales well with T $_{c}^{2}$ and is found to be similar in a number of different layered superconductors.
