Answer:
2.3x10⁷ W/m²
Explanation:
The intensity (I) of a laser is its potency (P) divided by the area (A) that it is affected. The potency is the energy applied (or absorbed) in a period, thus id 91.0% of the energy is absorbed, so:
E = 0.91*540 = 491.4 J
And,
P = E/t, where t is the time in seconds
P = 491.4/4.00
P = 122.85 J/s
P = 122.85 W
The are of a circular spot is:
A = (π/4)*d²
Where d is the diameter. Thus, with d = 2.60 mm = 0.0026 m
A = (π/4)*(0.0026)²
A = 5.31x10⁻⁶ m²
I = P/A
I = 122.85/5.31x10⁻⁶
I = 2.3x10⁷ W/m²
