Apparatus, including a detector array, analog-to-digital converter, a microprocessor including a memory, and display for determining the total energy, divergence and position of an applied laser beam from a single laser pulse. The detector array is coupled to the microprocessor and computer memory by way of the analog-to-digital converter. The microprocessor controls the detector array scanning and computes the values for the desired characteristics. The display provides for a numerical, alpha-numerical or printed record of the calculated values. A method of determining the total energy, relative position and divergence is also provided.
