Abstract
A wire resistor is mounted so that its position may be rotated continuously. The resistance of the wire (when subjected to the high energy laser beam) is measured as a function of position by use of a bridge circuit for determining the resistance and a potentiometer for determining the position. This device may also be used to analyze moderate power (greater than 1 watt) cw laser beams but here it is necessary to chop the beam in order to obtain the data.
