comment When do we see particles to be in a superposition of energy states?
The statements in the first para will also hold true for statistical mixtures of the type $|a|^2 |E_1\rangle \langle E_1| + |b|^2 |E_2\rangle \langle E_2|$. To verify whether the prepared state is a superposition $a |E_1 \rangle + b |E_2 \rangle$ unambiguously, one must be able to see interference. As mentioned in the comment by user26143, this may be possible with say the position measurement.

comment Can we fire a single femtosecond pulse of light without an associated train of additional pulses? What sort of equipment allows for this?
With regards to the requirement of the broad spectral range, you could also try a supercontinuum source, such as one by pumping a photonic crystal fiber (PCF). For example, emission wavelengths in the range of 150-500 nm can be produced using gas-filled hollow-core PCF (opticsinfobase.org/oe/abstract.cfm?uri=oe-21-9-10942).

comment Estimating quantum efficiency of gated avalanche photodiode
The APD is configured to apply a deadtime $\tau_d$ of a fixed no. of gates after detecting an avalanche. I could change the gating frequency, so I chose $f_1 < 1/\tau_d$. And I also pre-checked the attenuation of the VOA for a range of powers (as $\lambda$ was not the standard wavelength for that VOA) to get the offset.
