What does it mean by laser pulse 10 nanosecond?
Or maybe you think a laser beam is a continuous stream of light, its not. The laser machine sends out chunks of beam, but so many so fast (1x10-7 in your case).touqra said:What does it mean by laser pulse 10 nanosecond?
Yeah. You almost have to consider it to be a photonic machine gun. The pulse duration can be equated to the length of a bullet, and the pulse frequency to the firing rate. That's the reason that you can get such enormous energy density in a laser; if you take a couple of hours to pump 5 megawatts into a capacitor bank, then release it in a millisecond chopped into some picosecond pulses...Mk said:Or maybe you think a laser beam is a continuous stream of light, its not.

No; sorry about the confusion. As Zapper said, it's really very basic. The duration, which your original question was about, is how long the laser fires for one particular pulse. The frequency that I referred to is simply how many of those pulses are fired per second.touqra said:Do you mean the pulse frequency, as in the frequency, calculated as:
[tex]frequency = \frac{lightspeed, c}{duration, 10ns} [/tex]

That is what I meant. Thanks for the reminder not to use sloppy language here.Geoff St. Germaine said:(unless you have a 5 MW power supply that you use to charge the bank and that's what you meant).
A laser pulse with a duration of 10 nanoseconds is a short burst of laser light that lasts for 10 billionth of a second. It is a rapid and powerful burst of energy that is used in various scientific and industrial applications.
A laser pulse with a duration of 10 nanoseconds is typically produced by using a laser system that emits short bursts of coherent light. This can be achieved by using a mode-locked laser, which produces a series of ultra-short pulses with a duration of 10 nanoseconds or less.
A laser pulse with a duration of 10 nanoseconds has a wide range of applications in various fields such as materials processing, laser spectroscopy, medical imaging, and high-precision measurements. It is also used in research for studying ultrafast processes in atoms and molecules.
The duration of a laser pulse is directly related to its energy and power. A shorter pulse duration means a higher peak power and energy, while a longer pulse duration means a lower peak power and energy. This is why 10 nanosecond laser pulses are often used for high-power applications.
One of the main advantages of using a laser pulse with a duration of 10 nanoseconds is its high peak power and energy, which makes it suitable for applications that require precise and rapid energy delivery. Additionally, it allows for the study of ultrafast processes and has a wide range of applications in different fields.
