Some neodymiun-glass lasers can provide 100 TW of power in 1.0 ns pulses at a wavelength of 0.26 um. How much energy is contained in a single pulse?
To determine the energy contained in a single pulse of a neodymium-glass laser, you can use the formula:
Energy = Power x Time
Given that the power output of the laser is 100 TW (terawatts), and the time duration of the pulse is 1.0 ns (nanosecond), we can convert these values to their corresponding SI units:
Power = 100 TW = 100 x 10^12 W
Time = 1.0 ns = 1.0 x 10^-9 s
Now we can calculate the energy:
Energy = Power x Time
= (100 x 10^12 W) x (1.0 x 10^-9 s)
= 100 x 1.0 x 10^12 x 1.0 x 10^-9 J
= 100 J
Therefore, a single pulse of the neodymium-glass laser contains 100 joules of energy.
