Laser Peak Power Calculator

Notes: This calculator assumes square pulses. For other shape pulses, the result will not be completely accurate. (You can see your precise laser pulse shape with a fast photodiode like the FPS-1) Tophat calculations are for ideal tophat laser beams. For beams that are not 100% uniform, the peak power/energy density will be higher.

Do lasers lose power over distance?

The amount of power lost depends on the wavelength of the laser and the type of material that it travels through. The longer the distance traveled by the laser, the more significant the losses. As an example, we might look at the atmospheric transmittance chart, which informs us which wavelengths the atmosphere lets through (100% is the max ...

Laser

A laser is called continuous-wave if its output is nominally constant over an interval of seconds or longer; one example is the steady red beam from a laser pointer. Pulsed lasers concentrate their output energy into brief high-power bursts. These lasers can fire single pulses or a series of pulses at regular intervals.
