Expert Answer

Step 1

Percent efficiency can be defined as the energy produced divided by the energy consumed multiplied by 100.

Step 2

Here, we have a laser which consumed 200.0 Watts of electrical power.

To produce 1.34 x 10^19 photon/second of wavelength = 1050 nm

We have to calculate first the power obtained by the photons

Then from the cons...
