What factors determine optical energy?

Laser's power, frequency, and bandwidth
Laser's power, spot size, and pulse duration
Laser's intensity, color, and temperature
Laser's brightness, spot size, and frequency

The correct answer is: Laser's power, spot size, and pulse duration

Optical energy is determined by a combination of factors, including the laser's power, spot size, and pulse duration. A laser's power, or output, determines how much energy it produces. The spot size, or the size of the laser's focal point, affects the concentration of energy. And the pulse duration, or the length of time that the laser is on, determines the total amount of energy delivered over that time period. While the other options may seem plausible, they are not directly related to the determination of optical energy. For example, intensity and brightness are other ways to describe power and do not add any new information. Color is also not a determining factor for optical energy, as different colors of light can have the same amount of energy. Temperature may affect some components of a laser, but it is not a factor in the measurement of optical energy. Frequency, while a relevant factor, is not the only determining factor as it is in option A. Therefore, option B is the best choice for determining optical energy.
