Suppose a certain laser can provide 140 TW of power in 0.96 ns pulses at a wavelength of 0.25 ?m. How much energy is contained in joules in a single pulse?

I will give 5 stars for the correct answer

Expert Solution

1 ) A laser can provide a Power P = 140.0 TW

= 140.0 *10^12 W

time t = 0.96 ns

= 0.96*10^-9 s

Energy contained in a single pulse is

E = P * t

= 140.0 *10^12 W * 0.96 *10^-9 s

= 13.4*10^4 J

A certain laser emits monochromatic pulses approximately 1.25x10^15 photons every sec. a detection device is placed in front of the beam and measures the energy output over span of 1 min. The device reports a total input energy of 25 mJ. Determine wavelength of the emitted photons and the power of the beam

Fundamental of power electronics: In a certain application, an unregulated dc input voltage can vary between 18 and 36 V. It is desired to produce a regulated output of 28 V to supply a 2 A load. control circuit automatically adjust D to maintain the constant output voltage and current. All ideal components. Hence, a converter is needed that is capable of both increasing and decreasing the voltage. Since the input and output voltages are both positive, converters that invert the...

Suppose that 27% of all steel shafts produced by a certain process are nonconforming but can be reworked (rather than having to be scrapped). (a) In a random sample of 167 shafts, find the approximate probability that between 30 and 54 (inclusive) are nonconforming and can be reworked. (b) In a random sample of 167 shafts, find the approximate probability that at least 48 are nonconforming and can be reworked.

Corona: Suppose that all people can transmit the corona virus with a certain probability p to another person without knowing it. Furthermore, assume that wearing a face mask reduces the probability that you transmit the virus to another person to zero but does nothing to protect yourself (both of these assumptions are not true in reality). Catching the virus with probability p gives you a payoff of -100 * p. Wearing a face mask is obviously inconvenient and reduces your...

The values of certain types of collectibles can often fluctuate greatly over time. Suppose that the value of a particular limited edition figurine is found to be able to be modeled by the function ?(?) = −0.01?4 + 0.47?3 − 7.96?2 + 49.18? + 65 for 0 ≤ ? ≤ 20 where ?(?) is in dollars, t is the number of years after the figurine was released, and ? = 0 corresponds to the year 1999. a) What was the...

Suppose a property can be bought for $2,500,000 and it will provide $200,000/year net cash flow forever, and you can borrow a perpetual interest-only mortgage secured by that property at a 7% interest rate, up to an amount of $950,000. (a) Does this present “positive” or “negative leverage,” and (b) why? (c) Do you think that the use of leverage, in this case, will increase the NPV of the investment for the equity investor in the property? (d) Why or...
