This calculator provides a straightforward method for calculating the average power of pulsed lasers, facilitating its application across a wide range of disciplines and industries. Presented here are the relationships among some basic quantities often needed when working with laser pulses and power or energy meters. The laser we'll use is a 1064 nm YAG laser, emitting 30 ns wide 1200 mJ pulses at a rate of 40Hz. Power Density Calculator for Electro Optics. When it comes to pulsed lasers, instead of having a continuous flow of energy, photons are delivered to a target in short pulses separated by rest periods. The CW laser's output power equals the pulsed laser's average power. Divide the energy per pulse by the pulse width (in time) and you will get the peak power. A 100W laser, whether it is continuous or pulsed, has an average power of 100W. There are two basic laser beam profiles, Gaussian and Flat top. Understanding the average power of a pulsed laser is critical to ensuring the safety and effectiveness of the laser in use. Gaussian beam intensity is calculated for the 1/e^2 (13.
