1 eV is not equivalent to 11,600K, rather it is equivalent to 1.602e-19J. Both eV and J are unit of energy. K is unit of temperature. Sometimes, you can see people using 11,600K to describe eV. This is because people are using Boltzmann constant k = 1.381e-23 J/K, which links the temperature to molecular kinetic energy. The conversion is numerical and does ...

Binding energy is usually not associated with temperature. Only a kinetic energy of random motion is related to temperature. You can imagine a bunch of particles at rest. Then go to some moving frame of reference. Now all particles are moving in the same direction and they have some kinetic energy. However, we will not say that the temperature of the system ...

In specifications of the damage threshold of optical components (laser damage threshold, LDT), "per cm" means "per cm of beam diameter", with the assumption of a beam with a circular cross section hitting the optical surface. This is related to heating of the material; with a small spot diameter, the heat can leave more easily from the spot (or cylindrical ...

This page http://cvilaseroptics.com/custom/LIDT seems to contain very similar numbers for the induced damaged threshold, $$2\,{\rm J}\cdot {\rm cm}^{-2}, \quad 20\,{\rm ns}, \quad 20\,{\rm Hz}$$ Note that the power of the centimeter is $-2$, minus two. This simply means the amount of energy (two joules) deposited per unit area (squared centimeter) in ...
