Laser energy monitor |
| abstract |
A sensor head for monitoring radiated laser energy is disclosed which uties a transparent scatter plate placed in the path of the laser beam. A plurality of regularly spaced photodetector diodes are secured to its outer edge. The scatter plate and photodiode configuration are contained in a mounting bracket and frame assembly which permits its attachment to a front of a variety of laser systems without requiring modification of those systems. As radiation from the incident laser beam is transmitted through the plate, a small portion of the laser energy is coupled to the diodes via microscopic scattering sites in the plate. The signal output from the four diodes is combined by signal summing to provide a measure of the energy at peak power output of the laser without distorting or perturbing transmitted beam. |
